Re: How to get argp to print standard fields in the target language?

Since all usage of argp has the same translation strings, they could
be a part of files distributed as a package with the OS.  This would
be easy for developers and space efficient.  From my current
understanding, this does not work with gettext as implemented because
simultaneous domains as described in
https://www.gnu.org/software/gettext/manual/gettext.html#Triggering do
not seem to be supported.  Should this be supported?  I'm looking at
this and I can brute force it as described and leave the same
ungoogleable problem for others.  What I imagine as the end result is
to "just" have argp have its strings translated as a part of the OS
distribution, so they'll translate on their own.

No, it would not help if, say, glibc would include these strings in the
libc.pot file. That's because there are other platforms (*BSD, mingw, etc.)
that don't have this .pot file and its translations.

Therefore these strings from argp-help.c need to be either in your
package's .pot file, or in a gnulib.pot file. There was an experimental
gnulib.pot file many years ago, but it was too cumbersome to keep up-to-date.
Therefore the only good option is to have these strings in your
package's .pot file.

Simultaneous gettext domains are supported. GNU clisp uses this feature,
as it has 2 gettext domains.
