Not only is this not safe (what if $2 doesn't have a trailing slash?), it
can't be done; the regex memory variables ($1, $2, $3, etc.) are read-only.
It's really irrelevant, though; the trailing slash can be left in, none of
the operators that deal with paths care about multiple slashes. This is
true for Unix and the special path handling in Windows; I'm not sure of the
various other operating systems.

The question is really moot, mkpath doesn't have a problem if the directory
already exists, so you don't need to check it.
