for simplicity, only the change owner may issue the command. for other
cases, you still need to go through an admin. the same is advisable for
batch requests, but do as you wish.

the regex is 

  /^(?:gerrit-)?bot:\h*(?:please\h+)?move\h+(?:back\h+)?to\h+(?:branch\h+)?([\w.]*\w)\b/im

which boils down to "bot: move to <branch>" at the start of any line of
a gerrit cover message.
