This looks funny. If you look at list_commands() that this patch is
mimicking, you will notice that the "trailing blank for clarity" is
done as part of the function, not done by the caller. I think it is
better done the same way.

The _only_ reason we have common-cmds.h as a separat file even
though it defines data (hence should not be included in more than
one *.c file) is because it is a generated file.
For this array, there is no reason to have it in a separate header
file. Just define it immediately before list_common_guies_help()
function that is the sole user of the array.
The function can live in builtin/help.c as a static, without
touching global help.c nor help.h, no? Is there a reason why it
should be callable from other places?
