Hi Reuben,

I am in favour of the idea. I won't have time to check the patch in the
next little while because of travel. A few comments though:

I would keep the options to long options only for now, rather than use an
arbitrary unused letter.

The copyright assignment is a must before any patch can be accepted
that is longer than 10 or 15 lines, I forgot the exact number.

There have been some talk on this list about a year or so ago regarding
lazy dynamic linking of libpcre, but I don't remember if it was
implemented or not. If not, I believe there is a general welcome for such
a patch.
