That would imply that it wasn't clear that the string of characters that
were not "." had to extend to the end of the string, as I'd intended, so
I need to fix that.  I also need to say "not `tt(.)' or `tt(/)'".


Remove a filename extension leaving the root name.  Strings with no
filename extension are not altered.  For this purpose, a filename
extension is a `tt(.)' followed by any number characters (including
zero) that are neither `tt(.)' nor `tt(/)' and that continue to the end
of the string.  For example, the extension of
`tt(foo.orig.c)' is `tt(.c)', and `tt(dir.c/foo)' has no extension.
