shlex is good if you need it, but for this specific use you
can probably do without it.  The keys must be identifiers,
given the use you make of them, so you do not need to cater
for their being quoted.  If you do need to allow spaces in
the filenames, then the quoting that shlex affords may indeed
be the soundest way, though (because line.split(None, 1) would
not remove the trailing \n the way line.split() does...].
