A "git submodule add ../sub" interprets "../sub" relative to the default
remote of the superproject. To be able to do that, a url for that remote
has to be set in the superprojects .git/config. If that is not the case
the command fails with:
"remote (origin) does not have a url defined in .git/config"
This neither mentions the relative repository nor that the .git/config of
the superproject is the one with the missing url. And as a novice user
could assume that relative paths would work just like absolute paths do
in the filesystem and run into this by accident, the message is not very
helpful.
So change that to
"Cannot resolve "../sub" relative to remote (origin), its url
is not set in .git/config"
to give the user a clue that "git submodule add" interprets a relative
path as being relative to its default remote, not the work tree.

What about this patch?
