 Make sure hg is really paranoid in serve --stdio mode. It used to be
 possible to get a debugger REPL by specifying a repo named --debugger.
   $ hg -R --debugger serve --stdio
   abort: potentially unsafe serve --stdio invocation: ['-R', '--debugger', 'serve', '--stdio']
   [255]
   $ hg -R --config=ui.debugger=yes serve --stdio
   abort: potentially unsafe serve --stdio invocation: ['-R', '--config=ui.debugger=yes', 'serve', '--stdio']

 Abbreviations of 'serve' also don't work, to avoid shenanigans.
   $ hg -R narf serv --stdio
   abort: potentially unsafe serve --stdio invocation: ['-R', 'narf', 'serv', '--stdio']
