Details:

When running msgfilter on a .po file that contains an empty msgstr, and the
command prints anything, then msgfilter will abort. The abort does not occur
however if the msgstr is non-empty, or if the command doesn't output
anything.

For example:

    msgfilter -i test.po cat #doesn't abort, empty msgstr prints nothing
    msgfilter -i test.po echo -n #doesn't abort, no output
    msgfilter -i test.po echo -n 'a' #aborts on empty msgstr
    msgfilter -i test.po echo #aborts on empty msgstr

I did a bit of debugging, and it seems that the abort is called from
pipe_filter_ii_execute in gnulib/lib/pipe-filter-ii.c:270, which doesn't make
much sense as that should only be called if setting the SIGPIPE signal handler
fails... which is totally unrelated to the output of the filter program?
