Hm, that certainly simplifies the implementation.  However, if a
project needs to modify Makefile.in.in, it has to be quite careful in
keeping all those copies in sync.  Or can we arrange to use just one
copy of it ?  Given the way po/Makefile is generate, I'd think it
would be possible...

While I'm at talking about Makefile.in.in changes, here are the
changes I had to make for Wesnoth:

- support for a format-specific xgettext-like tool for the wesnoth

 => surely it would be better if there were hooks to allow plugging
 such alternatives without having to modify the Makefile by hand.

- support for specifying a command to find the files to be scanned by
xgettext instead of hardcoding into POFILES.in.  Such files are
currently a simple list of shell commands such as find and echo.  But
I understand it may not be easy to make this fully portable to
non-unix archs.

If we ignore the portability issue for now, my idea for a
generalization would look like defining parsers in a file like:

xgettext        cat ${DOMAIN}.POTFILES.in
wmlxgettext     sh ${DOMAIN}.FINDCFG

What do you think ?
