What's wrong is a matter of perspective.

In the immediate sense, the problem is that g.mlist removes the header
lines with:

	| grep -vE '^-+$|files available' \

which doesn't allow for NLS. Checking for e.g. ">:$" would probably be
better (although technically both > and : are legal in map names, it
seems unlikely to occur in practice).

In a more general sense, the problem is that modules which output
information in machine-readable form are somewhat scarce compared to
modules which output in human-readable form.
