Subject: parse-options: make OPT_INTEGER's argh explicit
X-Git-Tag: v1.6.4-rc0~55^2~1
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=e3a0ca878457ecc70d0065802fcb0c6875c6b671;p=git.git

parse-options: make OPT_INTEGER's argh explicit

OPTION_INTEGER hardcodes its argh member to be "n", but the decision is
hidden deep in usage_with_options_internal(). Make "n" the default argh
for the OPT_INTEGER macro while leaving it undecided for the OPTION_INTEGER
enum.

This makes it less surprising to users that argh is "n" when using the
OPT_INTEGER macro.
