[gettext] feature request: --use-first option for msgmerge

[Benno Schulenberg]

Hi,

When updating an existing PO file and wishing to replace any 
existing translations with ones from a compendium, one has to use 
the roundabout way of 'msgcat'.  To preserve everything else as is 
and just change the msgstrs that are different in the compendium, 
I'm using the following ugly script:

  # Standardize the messages for the second argument, using the
  # first argument as a compendium and the third argument as POT.

  grep -m1 -B555  '^$'  $2  >/tmp/po-header  &&
  msgcat --use-first --no-wrap  /tmp/po-header \
         $1  $2  >/tmp/po-catalog  &&
  msgmerge --no-wrap  /tmp/po-catalog  $3  >/tmp/po-new  &&
  grep -m1 -B22222 '^#~ msg' /tmp/po-new | sed '$d' | sed '$d'

Whereas I would like to simply do:

  msgmerge --use-first --no-wrap  -C $1  $2  $3

Is such a --use-first option to msgmerge feasible?
