I added missing final full stops in the commit message, and tweaked your
patter a bit. In particular, I removed the call to `string?', since
I don't think `find-files' can return a non-empty list with anything not
being a string.Let me know if you think I'm wrong.

Patch applied. Thank you.

Regards,

Use regex to find emacs executable. This works even when the version is
changed by package transformations (ex: version=git.master)
