The //= operator is mentioned in perl581delta.pod, it seems, and
none of our Perl scripted Porcelains seems to use it yet.  Is it
safe to assume that everybody has it?

This operator is new in Perl 5.10.  If you want the code to work on
RHEL/CentOS 5, you need to avoid it, since they only have 5.8 available.
