Compare string lengths when parsing the snapshot mask

Browse Source 
We used to rely on the result from strncmp() without comparing the length of
the strings involved. Even worse, any single-character format specifier would
enable zip-format due to the optional '.'-prefix since the length of the
mask then would become zero.
