Comment and uncomment regions

[Michael J. Manning]

Dear Tony and Rich

I have bound "TeX-comment-region" to "C-c;" and "Tex-un-
comment-region" to "C-c:".

I have noticed that these bindings fail to work, returning a 
"symbol's function is void:..." error if I start an R process under 
XEmacs without having opened and edited a *.tex file first. 

I guess that even though I think I am loading AucTeX when XEmacs 
starts up via "(load "tex-site")" in my init.el, and have bound the 
LaTeX comment functions to keys in the global map, the comment 
functions do not actually get loaded until LaTeX mode is started, 
which happens when a *.tex file is edited...

It occured to me to use the standard emacs command "comment-
region" in place of "TeX-comment-region", however I don't seem to 
have the command "uncomment-region" in my XEmacs, and "kill-
comment" kills the comment along with the line commented out 
rather than merely removing the comment character.
