I'll have to remember that one. It doesn't really fit my current use
case, but there are others where it would work nicely.

However, cmd.Cmd does not provide command recall and
editing. According to the page above, that's provided by the readline
module:

     If the readline module is loaded, input will automatically
     inherit bash-like history-list editing (e.g. Control-P scrolls
     back to the last command, Control-N forward to the next one,
     Control-F moves the cursor to the right non-destructively,
     Control-B moves the cursor to the left non-destructively, etc.).
