Version 0.2

Strip terminating NULL characters from the git commands

This is needed in order to prevent having ^A outputted in the git tags strings, because the system() function in vim is supposed to replace all NUL characters with SOH (0x01); see :help system.

The previous version of the script was working fine in 7.3 even without stripping the terminating NULL, but in 7.4 the behavior changed, see:
