tar_git's parameter token fails to filter for /

[Olf0]

Using <param name="token">/</param> does not filter at all: Any git-tag seems to be accepted.

Actually tar_git's imponderabilities made me using git-tags in the form %release/%version, which works well. Now I want to ensure, that only git-tags in this form are used by the SailfishOS-OBS. This does not seem to work, in contrast to e.g. token's which comprise only lowercase letters.
