That's nice to hear. I like supporting small groups of users.

Sounds like a good idea.

I guess the spell checking only works for ASCII compatible encodings,
thus not for EBCDIC. You can perhaps try if it works at all. If not
it's better to disable, so that Vim doesn't crash when someone tries to
use it.

You need to adjust the configure script for this.

Should be. Another solution is to skip the binary search and use linear
search.

I'm not so worried about the tests. The more of the real problems you
can fix the better.
