I expected 'project-switch-use-global-map' to be used
by 'project--switch-project-command' without the need
to customize 'project-switch-commands'.

Because the length depends on the deepness of the project root.

I'd prefer keeping only [executing in ...] because it's useful
to confirm in which directory the command will be executed.
But all available keys are usually useless except in such modes
as help-quick for novices.
