clone: handle empty config values in -c
"git clone --config" uses the following incantation to add an item to
a config file, instead of replacing an existing value:
git_config_set_multivar_gently(key, value, "^$", 0)
As long as no existing value matches the regex ^$, that works as
intended and adds to the config. When a value is empty, though, it
replaces the existing value.
Noticed while trying to set credential.helper during a clone to use a
specific helper without inheriting from ~/.gitconfig and
/etc/gitconfig. That is, I ran
git clone -c credential.helper= \
-c credential.helper=myhelper \
https://example.com/repo
intending to produce the configuration
[credential]
helper =
helper = myhelper
Without this patch, the 'helper =' line is not included and the
credential helper from /etc/gitconfig gets used.
