It is possible to break your repository config by creating an invalid key. The
config parser in turn chokes on it.
$ git init
Initialized empty Git repository in /tmp/gittest/.git/
$ git config .foo false
$ git config .foo
fatal: bad config file line 6 in .git/config
This patch makes git-config reject keys which start or end with a dot, adds
tests for these cases and also fixes a typo in t5526-fetch-submodules, which
was exposed by the new check.
Signed-off-by: Libor Pechacek <lpechacek@xxxxxxx>

Added tests for the cases checked, made git_config_parse_key consistently
return -2 when the key is invalid. Applies on top "Sanity-check config
variable names".
