Man-DB fails 2 tests with Groff-1.21

[Matthew Burgess]

Here's the abridged output from 'make check':

make[3]: Entering directory `/sources/man-db-2.5.9/man/de'
PASS: man1/apropos.1
man -E UTF-8 -l ./man1/man.1 produced error output:
warning: file `<standard input>', around line 134:
FAIL: man1/man.1

make[3]: Entering directory `/sources/man-db-2.5.9/man/it'
PASS: man1/apropos.1
man -E UTF-8 -l ./man1/man.1 produced error output:

FAIL: man1/man.1

And here's upstreams response to my report:

...you might just disregard the failing tests for now until I release man-db 2.6.0. They don't indicate a problem in the installed package (except for a minor one in man-db's own manual pages). While this was triggered by groff changing the format of its warning messages slightly, it's not a bug in groff either.

Fixed in r9448.
