Allow specifying multiple domains for makemessages command.

[c v t]

(The left-over part of #17181..)

Currently, to update / compile catalogues for both django and djangojs domains, you need to run makemessages and compilemessages twice:

django-admin.py makemessages -d django
django-admin.py makemessages -d djangojs

It would be lovely to be able to run this in one command, either:

django-admin.py makemessages -d django,djangojs

or:

django-admin.py makemessages -d django -d djangojs

(Currently, the first version gives an error; the second version silently ignores the first -d option, in this example it would just regenerate djangojs)

Apparently this was abandoned as per https://code.djangoproject.com/ticket/17181#comment:9. It may be that the current code allows an easier implementation. We would have to see a patch to judge that. Do you plan to provide one?

Thanks for this ticket.

compilemessages doesn't have domain argument.

Supporting multiple domains in makemessages can still be clunky, because they handle different extensions etc. It's probably not worth to add a complexity here.
Closing for now, nevertheless, if you would like to provide a patch we can evaluate it and reopen the ticket if consensus is reached.
