   3 # Usage:    ssh git@host symbolic-ref <repo> <arguments to git-symbolic-ref>
   4 #
   5 # allow 'git symbolic-ref' over a gitolite connection

   7 # Security: remember all arguments to commands must match a very conservative
   8 # pattern.  Once that is assured, the symbolic-ref command has no security
   9 # related side-effects, so we don't check arguments at all.
  10
  11 # Note: because of the restriction on allowed characters in arguments, you
  12 # can't supply an arbitrary string to the '-m' option.  The simplest
  13 # work-around is-to-just-use-join-up-words-like-this if you feel the need to
  14 # supply a "reason" string.  In any case this is useless by default; you'd
  15 # have to have core.logAllRefUpdates set for it to have any meaning.
