Well, this code snippet has its history. Initially, it was (and still
is) used in the Tramp git repository, file aclocal.m4. And that code
snippet is also propagated to trampver.el via template trampver.el.in.

If you want to improve the code, please change only these two files. The
Tramp git repository is located at
<git://git.savannah.gnu.org/tramp.git> (see also the Tramp manual).

This is a nice extension :-)
