;; Similar to path->string, except when the path is relative to the
;; main collects directory, which returns a string with just the
;; relative subpath inside collects. Used for producing less verbose
;; printouts during compilation, so the input path is usually
;; complete, otherwise it can be ambiguous, so use only when it's
;; clear from the context what path is shown. (To be used only for
;; human-readable output.) Generalized for any base directory and an
;; indicative prefix.
