Martin, can you please explain what cannot be performed by msggrep (apart
from Perl regular expressions)?
Bruno Haible has recently developed a libgettextpo library (part of
gettext) containing handful functions for applications which have to
read/write/parse PO files.  Maybe it is worth writing a XS module
to use this library?  This way, one shouldn't care about comments and
flags, but OTOH XS modules are architecture dependent.
As always, this is just a thought, I did not investigate deeply ;)
