Allow 'general--print-map' to print keymaps as commands

[SqrtMinusOne]

The current implementation of general--print-map sometimes prints broken Org Tables for me:

| key         | command                    | previous |
|-------------+----------------------------+----------|
| =SPC ?=     | ~which-key-show-top-level~ | ~nil~    |
| =SPC E=     | ~eval-expression~          | ~nil~    |
| =SPC SPC=   | ~nil~                      | ~nil~    |
| =SPC SPC x= | ~(keymap #^[nil nil keymap |          |
#^^[3 0 pop-global-mark ~|~2~|
|=SPC a=|~nil~|~nil~|
|=M-u=|~universal-argument~|~nil~|
|=SPC P=|~nil~|~nil~|
|=SPC P s=|~profiler-start~|~2~|
|=SPC P e=|~profiler-stop~|~2~|

Because the command in the 4th row has a linebreak.

This change removes unnecessary linebreaks from the result of the format expression, so that the case above works correctly.

| key           | command                                              | previous                                             |
|---------------+------------------------------------------------------+------------------------------------------------------|
| =SPC ?=       | ~which-key-show-top-level~                           | ~nil~                                                |
| =SPC E=       | ~eval-expression~                                    | ~nil~                                                |

| =SPC a=       | ~nil~                                                | ~nil~                                                |
| =M-u=         | ~universal-argument~                                 | ~nil~                                                |

Hmm, it seems like this part of the package doesn't have tests...

Thanks. That's fine. I don't plan to add tests or new functionality for this code (only bugfixes) since there is annalist.
