Yes I would.  But it will take me a long time to make it as I
understand very little of Makefiles.  So give me half a year.

No need to be afraid.  Mistakes may be made.  I see you
already have introduced the ability to decouple 'make dist'
from 'make update-po', and 'make update-po' from 'make
tralala.pot'.  I can understand why a maintainer would want
the first one, but I fail to grasp the use of the second one?

If necessary, we can make the same conditional decoupling
between GMO and PO files, or whatever it's going to be.

Because I'm not a maintainer, I'm a user, I never run 'make dist',
just 'make' and 'make install'.  That should cover everything, no
matter what file I change.  The only thing that should be a separate
and independent target is 'make POT', because PO files don't acquire
new translations automatically, there is no point in updating the POT
file if you can't acquire new PO files -- you have to be a maintainer:
you run 'make POT', send it out to translators, go to sleep, wake up a
week later, pull in the updated PO files, and then run 'make dist'.

But... shouldn't then all "CATALOGS" be replaced with "POFILES" in that
stamp-po comment?  Otherwise it doesn't make sense to me.
