[PATCH 2/4] OPT__VERBOSE(): clarify its expected use by using OPT_COUNTUP

[Junio C Hamano <gitster@pobox.com>]

The parseopt parsing for OPT__VERBOSE() is implemented in terms of
OPT_BOOLEAN() and users of it do take advantage of the "counting up"
behaviour to implement increasing levels of verbosity by
differentiating "git cmd -v" and "git cmd -v -v".

Clarify this by explicitly using OPT_COUNTUP() instead.
