Subject: fix update-hook-example to work with packed tag references
X-Git-Tag: v1.5.6.1~1
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=df79b9fdb863648fe27771ac373adb665cab066e;p=git.git

fix update-hook-example to work with packed tag references

The update-hook-example used 'test -f' to check the tag present, which
does not work if the checked reference is packed. This check has been
changed to use 'git rev-parse $tag' instead.
