parseopt: prevent KEEP_UNKNOWN and STOP_AT_NON_OPTION from being used together
As suggested by Junio, disallow the flags PARSE_OPT_KEEP_UNKNOWN and
PARSE_OPT_STOP_AT_NON_OPTION to be turned on at the same time, as a
value of an unknown option could be mistakenly classified as a
non-option, stopping the parser early. E.g.:
git cmd --known --unknown value arg0 arg1
The parser should have stopped at "arg0", but it already stops at
"value".
This patch makes parse_options() die if the two flags are used in
combination.
