[nmh-workers] Stupid 'pick' question...

[Valdis Klētnieks]

So.... trying to work with the linux-kernel mailing list firehose (800-1500
messages a day), and hitting a problem with 'pick'.

Am trying to match all messages from a given person with a given part of
a subject line.

pick -from <address> -subject '\[PATCH [45]\.[0-9]'

*almost* does what I want - catch all messages that have '[PATCH 4.9]'
or '[PATCH 4.14]'  or '[PATCH 5.0]'.  However, it *also* catches messages
of the form 'Subject: Re: [PATCH ....' which is unacceptable for the use case
in question.

So I tried an anchored search using -subject '^\[PATCH [45]\.[0-9]' but that
results in nothing matching. So much for this from the manpage:

       A modified grep(1) is used to perform the matching, so the  full  regular
       expression  (see  ed(1))  facility  is  available  within  pattern.  With
       -search, pattern is used directly, and with the others, the grep  pattern
       constructed is:

So is ^ to anchor the search in fact unsupported?  Broken? I'm using it wrong?

Oddly enough, $ for tail-anchor seems to work:
