I think this is not a bug, it's the documentation that is not clear
here. The above is only useful in conjunction with -A in which case
the description given with -d is shown as timeout text.

That's a point I do not understand. Looking at the code it's clear to me
why this have to be two commands, but I think it should be possible to
combine the select option with the show option. Furthermore I think the
-S option is quite useless. -S seems to used only to let the -n option
Overall it's not very clear which options exist and which options take
an argument. I've collected them and here is the result:
-m <menuname> specify menu to work on
-l list existing menus
-s show menu
-a Add a menu or, when -e is given additionally, add a menu entry
-r remove a menu
-d <description> description, in conjunction with
-a -e: Menu text to show
-A: timeout text to show
-A <delay> Autoselect selected entry in <delay> seconds
-c <command> run <command> when an entry is selected
-R reentrance, used with -a, do not leave the menu after
an entry is selected
-b 0|1 box entry. used with -a, add a yes/no entry
-e when given with -a, add a menu entry. When given with
-l, additionally to the menu also list the entries
-S -n <num> select entry <num>, starting at 1. Seperate command,
NOT together with actually showing the menu
I think we should add this to the help text for the menu command, or
even better, replace the docs and the code for -S -n <num> with a plain
