Exit status of git show-ref --verify

Exit status of git show-ref --verify

[Marc Legendre]

Hi,

I stumbled upon a small discrepancy between the documentation of git-show-ref
and its actual behavior. The documentation of the `--verify` flag of
git-show-ref says:

  "If nothing matches, 'git show-ref' will return an error code of 1"

Yet it seems to return 1 only if it is also called with --quiet. Tested with
the `next` branch:

  [~/dev/git] $ ./git show-ref --verify refs/heads/tagada
  fatal: 'refs/heads/tagada' - not a valid ref
  [~/dev/git] $ echo $?
  128

  [~/dev/git] $ ./git show-ref --quiet --verify refs/heads/tagada
  [~/dev/git] $ echo $?
  1
