Change request: file names

[Tim Van Holder]

I'd like to request the following changes in file names for some future
version of autoconf:

-) use acversion.in, not acversion.m4.in
   reason: not all systems support multiple dots in filenames

A similar problem exists in the man directory (the config.guess and
config.sub man pages), but that is not so easily solved.

-) use .in instead of .pl/.sh for the script templates
   reason: DOS (and probably Win9x/NT as well) can/does treat
   .sh and/or .pl as executable extensions. So when bootstrapping
   autoconf, you may end up running the templates instead of the
   scripts (once the scripts have been generated, 'autoconf' will
   usually be used before autoconf.sh, but that does not entirely
   negate the problem).
   It would also be more consistent with the naming conventions
   autoconf uses for templates (name + .in).
