Before
63e95beb0 (2016-04-15, submodule: port resolve_relative_url from
shell to C), it did not matter if the superprojects URL had a trailing
slash or not. It was just chopped off as one of the first steps
(The "remoteurl=${remoteurl%/}" near the beginning of
resolve_relative_url(), which was removed in said commit).
When porting this to the C version, an off-by-one error was introduced
and we did not check the actual last character to be a slash, but the
NULL delimiter.
Reintroduce the behavior from before
63e95beb0, to ignore the trailing
slash.
