revision: drop useless string offset when parsing "--pretty"

Once upon a time, we parsed pretty options by looking for
"--pretty" at the start of the string, and then feeding the
rest (including an "=") to get_commit_format. Later, commit
48ded91 (log --pretty: do not accept bogus "--prettyshort",
2008-05-25) split this into a separate check for "--pretty"
versus "--pretty=".

However, when parsing "--pretty", we still passed "arg+8" to
get_commit_format. This is useless, since it will always
point to the NUL terminator at the end of the string. We can
simply pass NULL instead; both parameters are treated the
same by get_commit_format.
