Subject: builtin/log.c: separate default and setup of cmd_log_init()
X-Git-Tag: v1.7.5.1~7^2~2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=ef803fd4b09bca707c7c27669a2789bb050b488c;p=git.git

builtin/log.c: separate default and setup of cmd_log_init()

cmd_log_init() sets up some default rev options and then calls
setup_revisions(), so that a caller cannot set up own defaults: Either
they get overriden by cmd_log_init() (if set before) or they override
the command line (if set after). We even complain about this in a
comment to cmd_log_reflog().

Therefore, separate the two steps so that one can still call
cmd_log_init() or, alternatively, cmd_log_init_defaults() followed by
cmd_log_init_finish() (and set defaults in between).

No functional change so far.
