[PATCH] get_remote_url(): use the same data source as ls-remote to get remote urls

["Uwe Kleine-König" <u.kleine-koenig@pengutronix.de>]

The formerly implemented algorithm behaved differently to
remote.c:remote_get() at least for remotes that contain a slash.  While the
former just assumes a/b is a path the latter checks the config for
remote."a/b" first which is more reasonable.

Hello,

with this patch git-request-pull.sh (== the only in-tree user of
git-parse-remote.sh:get_remote_url()) could directly use

	git ls-remote --get-url

.  I guess you wouldn't want to remove git-parse-remote.sh:get_remote_url()
though?!  Maybe add a deprecation warning to it?  The same applies to
git-parse-remote.sh:get_data_source() that isn't used anymore already with this
patch.

Best regards
Uwe
