The translated manpage generation has moved from scripts to
Makefiles. This asists with conditional building as well, no
need to regenerate the German pgrep man page if both
the original pgrep.1 and man-po/de.po is not changed.
My Makefile-fu fails me on producing a cross-product or double
iteration for languages and man pages. Until that is solved
each man page is explicitly built. No big deal but it doesn't
look elegant in the Makefile. Languages will be picked
up automatically if they are found in man-po, man-po/top or
man-po/ps
The README describes the three-step process for translating
the files, incase I forget or someone else wants to update them.
The pot files for man-po are part of the extra_dist target so are
built at dist time. These used to be created as part of the dist-hook.
However it is better to control their builds in the Makefile so they
are conditionally built. It also means distcheck doesn't complain when
they are added to the CLEANFILES.
distcheck failed because the man-po scripts weren't sourcing or
escaping the directories correctly.
This is a partial fix, but at least distcheck is happy.
