I just imported current along the vendor branch into a CVS repository
(that had previously had older current and then netbsd-2-0 bits).

Besides the usual new files, updated files, and pseudo-conflicts, I
had a bunch of I lines in src/gnu/dist/binutils.
The .cvsignore file there lists *.gmo

Since the .gmo files are listed as:

da.gmo:          GNU message catalog (little endian), revision 0, 545 messages

is it safe to presume it's an error for them to be in the NetBSD
repository (and perhaps an error to be in binutils cvs/distfile?).

(It also strikes me that .cvsignore files from upstream sources
probably should be pruned before import, along with files that
shouldn't have been in the upstream sources, but I know I'm ignorant
of the history of why things are as they are, so this may well be
wrong.)
