Commit messages should be written in ChangeLog format[1], you can look
at previous commits for examples.

This commit should also be split into two separate commits, one adding
‘perl-file-next’, and the other adding ‘ack’.

Use ‘(file-name (git-file-name name version))’.

Try to make the synopsis as concise as possible, just “Lightweight,
taint-safe file-finding Perl module” should do.  See the ‘Synopses and
Descriptions’ section of the manual.

The description should contain one or more complete sentences.

We usually use ‘(string-append "v" version)’ instead of ‘format’.

Use ‘(file-name (git-file-name name version))’ (same as above).

What’s the reason for disabling the tests?

                                                   ^^
Unecessary whitespace, and missing period.
