parse-options: remove PARSE_OPT_NEGHELP

René Scharfe · gitster · commit cbb08c2e0b41 · 2012-02-28T11:48:11.000-08:00
PARSE_OPT_NEGHELP is confusing because short options defined with that
flag do the opposite of what the helptext says. It is also not needed
anymore now that options starting with no- can be negated by removing
that prefix. Convert its only two users to OPT_NEGBIT() and OPT_BOOL()
and then remove support for PARSE_OPT_NEGHELP.
