Btw, the place we show "-ex" on the screen is unfortunate, as it is
very hard to find it at first glance.  See how it is obscured by text
above and below it:

  --cd=DIR           Change current directory to DIR.
  --command=FILE, -x Execute GDB commands from FILE.
  --eval-command=COMMAND, -ex
                     Execute a single GDB command.
                     May be used multiple times and in conjunction

It would be much better if we reformat the output like this:

  --cd=DIR           Change current directory to DIR.
  --command=FILE, -x Execute GDB commands from FILE.
  --eval-command=COMMAND,
                 -ex Execute a single GDB command.
                     May be used multiple times and in conjunction
