When the origin URL of the superproject is itself relative, an operation
such as git submodule add, init or sync may result in either the
submodule.{name}.url configuration property of the superproject
referring to the incorrect location or remote.origin.url configuration
property of the submodule referring to the incorrect location or both
these conditions. In some cases, git submodule fails to update
the configuration and fails with an error condition.
The issue arises in these cases because the origin URL of
the superproject needs to be prepended with a prefix that navigates
from the submodule to the superproject so that when the submodule
URL is concatenated the resulting URL is relative to the working tree
of the submodule.
This change fixes handling for relative superproject origin URLs
for 6 cases:
foo
foo/bar
./foo
./foo/bar
../foo
../foo/bar
In each case, the configuration properties in the superproject's
configuration and the submodule's configuration refer to the
correct, relative, location of the submodule's origin repo. In all cases,
the configured paths are relative to the working trees of the
repositories containing the configuration.
