Code clean-up.
* sg/revision-parser-skip-prefix:
revision.c: use skip_prefix() in handle_revision_pseudo_opt()
revision.c: use skip_prefix() in handle_revision_opt()
revision.c: stricter parsing of '--early-output'
revision.c: stricter parsing of '--no-{min,max}-parents'
revision.h: turn rev_info.early_output back into an unsigned int
