bug#45824: 27.1; term/screen.el not loaded when TERM=screen.xterm-256color

[Alex Hutcheson]

That behavior seems fine to me. In your example, Emacs would check 

for the following, in-order:

1. linux2.6.26.el
2. linux2.6.el
3. linux2.el

This seems like the right approach - try to match minor versions, but
if there is not a config for a specific minor version, then use the
config that matches the major version.

In this specific instance, it wouldn't actually find anything, because
there is no term/linux2.el file (just a term/linux.el file). This
could be resolved by also splitting between non-numeric characters and
numbers (so we would try linux.el as a step #4), but that's not
necessary to solve my specific problem.

Hm...  but wouldn't that possibly cause problems?  That is, if your TERM
is

linux2.6.26

then if we split on dots, then Emacs will first look for
"text/linux2.6.26.el", and then "term/linux2.6.el"...  and those are
indeed different terminfos as found on my system:

linux2.6
linux2.6.26

Now, there is no term/linux2.6.el, so perhaps this is irrelevant...  And
perhaps if there was a term/linux2.6.el, perhaps loading that would be
OK in this case?  Anybody got an opinion here?
