For that matter, merely adding the shell script file to po/POTFILES.in
is not getting anything picked up into the pot file.  I wonder if I have
to somehow teach xgettext to use --language=Shell for that one file.  In
fact, how _does_ one concatenate input strings from multiple languages
into a single .pot file?  Does it require multiple xgettext runs, one
per language?  And if that is the case, how do I represent that in the
autotooled build rules, such as po/Makevars.in?
