I missed a few of the syntax bugs ("%n" and these sort of things), but
also a broken link to the bugtracker URL (don't add spaces). Also I
reformated the long lines by running "make update-po" again.
Note by Jehan: this was initially contributed on the github mirror:
https://github.com/GNOME/gimp/pull/16
I would usually just tell them (which I did!) to post the patch to our
official bugtracker, and/or get in touch with the translation team, but
that was a brand new language support for the Windows installer so even
though I don't understand Indonesian, at least I know that doesn't break
anyone's previous work. Moreover setting up the new `.po` file requires
a bit of knowledge which a first-timer (contributor said he was) may
choke on. So that's me being nice and not wanting to waste a good first
contribution. :-)
I still had to manually copy-paste the translation since the translator
was attempting to modify setup.isl.in directly. Also I fixed a few
format syntax things (%n, %1, &Something… these sorts of things).
