Hello,

I would say that you are right, it seems that those font modifiers are
not supported, here is a patch.

                 my $new_font = $1;
                 my $arg = $2;

Anyway schroot manual pages are really terrible because of all these
formatting macros; IMO the attached schroot.1.in is much nicer to
translators.  If you also prefer the POT file generated by this one,
you could ask your upstream to make similar changes into other manual
pages.
