[Pdx-pm] Regex

[benh]

To pile on with everyone else, you can do the assignment all in one line:

  my ($count,$total) = map{s/,//g;$_} $s =~ m/Usage:([\d,]+) +of +([\d,]+) /

And that begs the larger question, is there a reason why you are both
checking and parsing $info at once? Given the current syntax I think
that even if the line is properly formatted as long as total is 0 then
you'll fail to run the block, is this what you want?  Or do you want
to also run this block given no messages out of a total number of
messages?
