Subject: config: Introduce functions to write non-standard file
X-Git-Tag: v1.7.8-rc0~141^2~17
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=5ec3118293931cf1fe8677f16449999cfbfc8b92;p=git.git

config: Introduce functions to write non-standard file

Introduce two new functions corresponding to "git_config_set" and
"git_config_set_multivar" to write a non-standard configuration file.
Expose these new functions in cache.h for other git programs to use.
