No, but it should definitely warn if the path doesn't exist (this is the
approach we took in BibDesk's TeX preferences, for instance). Trimming
or guessing at the user's intent for executables isn't generally safe.
IMHO, the best approach is to disallow direct entry of paths, and use
NSOpenPanel to guarantee a correct path. An NSPathControl is a more
modern way to represent paths, which I use in TeX Live Utility's
preferences. It works with an open panel or drag-and-drop.
