Subject: post-receive: fix warning in script for example when pushing deleted tags
X-Git-Url: https://git.atheridis.org/?a=commitdiff_plain;h=020673b8fddfc649e391831aee2e5562ac25210c;p=forks%2Fstagit.git

post-receive: fix warning in script for example when pushing deleted tags

the "new" variable would be zero:
	remote: fatal: bad object 0000000000000000000000000000000000000000

NOTE: when pushing new tags the "old" variable would be zero, this was
      already fixed.
