Subject: git_config_*: don't assume we are parsing a config file
X-Git-Tag: v1.5.5-rc0~174
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=c1867cea90f8e7ee8e1be3fc07a402dde1b2666d;p=git.git

git_config_*: don't assume we are parsing a config file

These functions get called by other code, including parsing
config options from the command line. In that case,
config_file_name is NULL, leading to an ugly message or even
a segfault on some implementations of printf.
