[GAP Forum] GAP mode for emacs

[Ivan Andrus]

This probably isn't the best place for this, but...

I have taken Michael Smith's gap-mode and made what I hope are improvements.  I'm using a very recent version of emacs however, so I may have inadvertently made it backwards incompatible.  I also haven't tested on Xemacs.  The code can be found at https://bitbucket.org/gvol/gap-mode/ so feel free to open an issue there if you have problems or suggestions (or contact me directly via email).

The main improvements are 
1. font-lock support
2. improved local statement functionality
3. beginning/end-of-defun functions
4. bug fixes in indentation
5. converting to defcustom's in gap-mode.el

I haven't touched gap-process.el yet, and may not for a while (I've got other stuff going on).  I did remove comint.el since that's been included with Emacs for a long time.  Running gap in Emacs seems to work for me, though I haven't tested it much.  Thus, if you need that functionality, please don't get rid of your old install!
