["Basil L. Contovounesios" <contovob@tcd.ie>]

Just some minor nits from me.

> Subject: [PATCH] Use same keys in project-switch-project as in
>  project-prefix-map
>
> * project.el (project-switch-commands): Convert to user option and
> change structure.
> (project-switch-use-entire-map): Add new option.
> (project--keymap-prompt): Adapt to change in project-switch-commands

Nit: Missing full stop.

> (project-switch-project): Use project-prefix-map instead of
> project-switch-commands to query valid commands.
