po4a dies on *.adocs with no translatable content

[suddenfall]

I have a complex adoc-project with many includes. Some documents just contains includes. On these files po4a fails, because it cannot create a corresponding pot.

My fix:

Adding the parameter --force-po to the command msggrep in the file po4a at line 1617.

Modified line:

my $cmd = "msggrep$Config{_exe} $split_pot_files{$master_pot} -o $outfile $pot_filename --force-po";

This seems all good. Please open a PR and claim the authorship.

I have never done this before. I hope that fit.
