I agree with the above, and to "the developers' job", I'll add that
"the" developer, Bram Moolenaar, has a full-time job which leaves him
little time to fix outright bugs in Vim, let alone add enhancements. We
are all lucky enough that he places such a fine (and oh, how well
documented! :-) ) editor at our disposition, at no cost to us (and yes,
we are encouraged to contribute to Bram's favourite charity, but if any
of us doesn't, his copy of Vim won't stop functioning just as well as it
does for those who do contribute).
The source code of Vim is all available, anyone has access to it; see
for instance by following the two last links of the summary of my Vim
page http://users.skynet.be/antoine.mechelynck/vim/ how I used to
compile Vim when I was on Windows and how I still do now that I'm on
Linux. No-one prevents you (Jean), or anyone else for that matter, from
altering the code to add any feature that suits your whim; once it works
to your satisfaction you can even publish your changes and ask to have
them added to the list of "unofficial patches" at
http://groups.google.com/group/vim_dev/web/vim-patches so that anyone
may profit by it. (Having your changes made part of "official" mainline
Vim requires, among others, convincing Bram that the change is a
valuable addition, that it doesn't beak backwards compatibility, that it
is free of obvious bugs, and that it obeys "Vim coding style". It's not
just any patch that can pass his judgment.)
Best regards,
Tony.
