The "if $4" is redundant here, because the regex above won't match at
all without it.  You probably want to make the $4 grouping optional by
following it with a "?" in the regex.

In both of the above you're donking the commit counter (the $5 part).
I'd like to go on record saying that I like that part of the version
number because it gives an easily human-readable way to determine if a
particular commit is older or newer.
