gettext: adding comments/keywords and grepping for those

[Karl Eichwalder]

Here's a feature request.

Maintaining compendium files it would be nice to have the possibility to
add user defined keywords as comments.  'msgattrib' looks like a
candidate for such an enhancement.  Then 'msggrep' can learn to look
through comments, too.

OTOH, for adding comments 'sed' might be good enough:

    sed -e '/^$/a\
    # Date: 2002-02-16' de.po

But how to extract those marked messages?  Using 'awk':

    awk '/^# Date: 2002-02-16/ { p = 1 }
    { if (p == 1) print }
    /^$/ { p = 0 } ' de.po

Perhaps a little bit fragile.
