Interesting, that was not the primary use case I was thinking to.

We could make this even easier by making COMMAND optional in:
   Usage: /SETTING... [COMMAND]
and giving no command means to repeat the previous command with the additional
given settings e.g. :
    (gdb) some command
    .... some command output
    (gdb) /e
        => executes /e some command

    (gdb) /e some command
    ... some command output
    (gdb) /p
       => executes  /ep some command

I guess we probably call dont_repeat () in / command
when no COMMAND is given.

Ok, will add some new lines in the v2 of the patch.

Thanks for the feedback
