Yeah. Doing:

  eval '$browser_cmd'

will do the whitespace-breaking we want, but it won't interpret actual
shell magic characters, which we need in order to be compatible with
other parts of git (which typically use "sh -c ..."). E.g.:

  foo=worked
  browser_cmd='echo $foo'
  # fail
  $browser_cmd
  # fail
  eval '$browser_cmd'
  # works
  eval "$browser_cmd"
