Subject: submodule sync: Update "submodule.<name>.url" for empty directories
X-Git-Tag: v1.7.3.3~18^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=33f072f;p=git.git

submodule sync: Update "submodule.<name>.url" for empty directories

If a submodule directory has not been filled by "git submodule update"
yet, then "git submodule sync" must still update the super-project's
configuration for submodule.<name>.url.

This situation occurs when switching between branches with a module from
different urls and other branches without the submodule.
