Notes:
- INSTALL seems to list wrong dependencies.
See https://bugzilla.gnome.org/show_bug.cgi?id=643473
And http://git.gnome.org/browse/meld/commit/?id=beb2de34b2483882b981bf04282cea2f29c52a43
- freshmeat and sourceforge don't seem to be updated (not even 1.4.0 is there),
so those got removed. DOWNLOADS is used from gnome.org.exlib
- tests are broken, so they got RESTRICTed.
make check just runs some QA on the sources (checks for tabs) and tries to
modify some files, which are not even there
make test needs X and fails because files are missing
