After cleanup introduced with previous commit, there is a need for
syntax-check rule taking care of return(). Regexp used in 'prohibit'
parameter is taken from the cleanup commit and modified so it fits
'grep -E' format. Semicolon at the end is needed, otherwise the regexp
could match return with cast.
No exception is needed thanks to files excused by default. The
exception is not even needed for python files because 1) when
returning a tuple, you can still omit parentheses around (unless there
is only one value inside, but that's very unusual case), 2) return in
python doesn't need semicolon at the end of statement when there is no
statement following (and statement following 'return' doesn't make
sense).
