[arch-projects] [namcap] [PATCH v3] makedepends: Make VCS matching more robust

[Michael Straube]

If a VCS source is renamed using the "::" syntax the makedepends are not
detected. If there are files starting with <name of VCS binary> in the source
array false positives are produced. See the gitlab package for example. Make
the matching more robust to avoid such issues.

v1 -> v2
Make it also work for e.g. git://

v2 -> v3
Return early if no vcs sources.
