The revision option parser recently learned about --end-of-options, but that's not quite enough for all callers. Some of them, like git-log, pick out some options using parse_options(), and then feed the remainder to setup_revisions(). For those cases we need to stop parse_options() from finding more options when it sees --end-of-options, and to retain that option in argv so that setup_revisions() can see it as well.
Let's handle this the same as we do "--". We can even piggy-back on the handling of PARSE_OPT_KEEP_DASHDASH, because any caller that wants to retain one will want to retain the other.
I've included two tests here. The "log" test covers "--source", which is one of the options it handles with parse_options(), and would fail before this patch. There's also a test that uses the parse-options helper directly. That confirms that the option is handled correctly even in cases without KEEP_DASHDASH or setup_revisions(). I.e., it is safe to use --end-of-options in place of "--" in other programs.
