Subject: [PATCH] taskset.1: fix description of -c option

Commit 42f15e9848dc07e86a2b80c742a0179aaced6c71 introduced a certain
inaccuracy in -c option description; it is not _the option with an argument_,
but it is the flag that changes interpretation of mask parameter.
The difference is almost not noticeable, but there are one corner case where it is:
taskset -c 1 -p $$
fails (but it would work if 42f15e was correct). Instead,
taskset -c -p 1 $$
works (but it should not have if 42f15e was correct).

P.S. argument parsing in taskset (and chrt) is rather unusual and confusing, and I'd voted to change it instead... unfortunately, people/scripts/... already depend on current behavior (and it is not outright broken, just unusual), so it is impossible.
