Yes, and this convention is documented.
Many options have long names starting with `-f' or with `-W'--for
example, -fmove-loop-invariants, -Wformat and so on. Most of
these have both positive and negative forms; the negative form of
-ffoo would be -fno-foo. This manual documents only one of these
two forms, whichever one is not the default.
