* Revision 1.1 2004/01/31 16:44:12 zrusin
* ISpell plugin.
*
* Revision 1.4 2003/08/14 17:51:26 dom
* update license - exception clause should be Lesser GPL
*
* Revision 1.3 2003/07/28 20:40:25 dom
* fix up the license clause, further win32-registry proof some directory getting functions
*
* Revision 1.2 2003/07/16 22:52:35 dom
* LGPL + exception license
*
* Revision 1.1 2003/07/15 01:15:04 dom
* ispell enchant backend
*
* Revision 1.2 2003/01/29 05:50:11 hippietrail
*
* Fixed my mess in EncodingManager.
* Changed many C casts to C++ casts.
*
* Revision 1.1 2003/01/24 05:52:31 hippietrail
*
* Refactored ispell code. Old ispell global variables had been put into
* an allocated structure, a pointer to which was passed to many functions.
* I have now made all such functions and variables private members of the
* ISpellChecker class. It was C OO, now it's C++ OO.
*
* I've fixed the makefiles and tested compilation but am unable to test
* operation. Please back out my changes if they cause problems which
* are not obvious or easy to fix.
*
* Revision 1.7 2002/09/19 05:31:15 hippietrail
*
* More Ispell cleanup. Conditional globals and DEREF macros are removed.
* K&R function declarations removed, converted to Doxygen style comments
* where possible. No code has been changed (I hope). Compiles for me but
* unable to test.
*
* Revision 1.6 2002/09/17 03:03:28 hippietrail
*
* After seeking permission on the developer list I've reformatted all the
* spelling source which seemed to have parts which used 2, 3, 4, and 8
* spaces for tabs. It should all look good with our standard 4-space
* tabs now.
* I've concentrated just on indentation in the actual code. More prettying
* could be done.
* * NO code changes were made *
*
* Revision 1.5 2002/09/13 17:20:12 mpritchett
* Fix more warnings for Linux build
*
* Revision 1.4 2002/03/06 08:27:16 fjfranklin
* o Only activate compound handling when the hash file says so (Per Larsson)
*
* Revision 1.3 2001/05/14 09:52:50 hub
* Removed newMain.c from GNUmakefile.am
*
* C++ comments are not C comment. Changed to C comments
*
* Revision 1.2 2001/05/12 16:05:42 thomasf
* Big pseudo changes to ispell to make it pass around a structure rather
* than rely on all sorts of gloabals willy nilly here and there. Also
* fixed our spelling class to work with accepting suggestions once more.
* This code is dirty, gross and ugly (not to mention still not supporting
* multiple hash sized just yet) but it works on my machine and will no
* doubt break other machines.
*
* Revision 1.1 2001/04/15 16:01:24 tomas_f
* moving to spell/xp
*
* Revision 1.2 1999/10/05 16:17:28 paul
* Fixed build, and other tidyness.
* Spell dialog enabled by default, with keyboard binding of F7.
*
* Revision 1.1 1999/09/29 23:33:32 justin
* Updates to the underlying ispell-based code to support suggested corrections.
*
* Revision 1.59 1995/08/05 23:19:43 geoff
* Fix a bug that caused offsets for long lines to be confused if the
* line started with a quoting uparrow.
*
* Revision 1.58 1994/11/02 06:56:00 geoff
* Remove the anyword feature, which I've decided is a bad idea.
*
* Revision 1.57 1994/10/26 05:12:39 geoff
* Try boundary characters when inserting or substituting letters, except
* (naturally) at word boundaries.
*
* Revision 1.56 1994/10/25 05:46:30 geoff
* Fix an assignment inside a conditional that could generate spurious
* warnings (as well as being bad style). Add support for the FF_ANYWORD
* option.
*
* Revision 1.55 1994/09/16 04:48:24 geoff
* Don't pass newlines from the input to various other routines, and
* don't assume that those routines leave the input unchanged.
*
* Revision 1.54 1994/09/01 06:06:41 geoff
* Change erasechar/killchar to uerasechar/ukillchar to avoid
* shared-library problems on HP systems.
*
* Revision 1.53 1994/08/31 05:58:38 geoff
* Add code to handle extremely long lines in -a mode without splitting
* words or reporting incorrect offsets.
*
* Revision 1.52 1994/05/25 04:29:24 geoff
* Fix a bug that caused line widths to be calculated incorrectly when
* displaying lines containing tabs. Fix a couple of places where
* characters were sign-extended incorrectly, which could cause 8-bit
* characters to be displayed wrong.
*
* Revision 1.51 1994/05/17 06:44:05 geoff
* Add support for controlled compound formation and the COMPOUNDONLY
* option to affix flags.
*
* Revision 1.50 1994/04/27 05:20:14 geoff
* Allow compound words to be formed from more than two components
*
* Revision 1.49 1994/04/27 01:50:31 geoff
* Add support to correctly capitalize words generated as a result of a
* missing-space suggestion.
*
* Revision 1.48 1994/04/03 23:23:02 geoff
* Clean up the code in missingspace() to be a bit simpler and more
* efficient.
*
* Revision 1.47 1994/03/15 06:24:23 geoff
* Fix the +/-/~ commands to be independent. Allow the + command to
* receive a suffix which is a deformatter type (currently hardwired to
* be either tex or nroff/troff).
*
* Revision 1.46 1994/02/21 00:20:03 geoff
* Fix some bugs that could cause bad displays in the interaction between
* TeX parsing and string characters. Show_char now will not overrun
* the inverse-video display area by accident.
*
* Revision 1.45 1994/02/14 00:34:51 geoff
* Fix correct to accept length parameters for ctok and itok, so that it
* can pass them to the to/from ichar routines.
*
* Revision 1.44 1994/01/25 07:11:22 geoff
* Get rid of all old RCS log lines in preparation for the 3.1 release.
