This is a bug report for perl from robin.barker@npl.co.uk,
generated with the help of perlbug 1.34 running under perl v5.8.1.
-----------------------------------------------------------------
[Please enter your report here]
This is an issue with C<config_re> in Config.pm
% perl -V:'?flags'
Surpring works and list all the .*flags config vars.
It works because the regexp used in config_re become
/^?flags=/
so the ? (optionally) undoes the ^.
Is this a neat feature, or should the -V:regexp only
accept valid regexps?
I have a patch for the latter case [attached].
