On Unix/POSIX, environment variables in file paths are typically not
handled as widely as tilde expansion, or by the same facilities (for one
thing, envar expansion is applicable to general strings, not just file
paths; I think this is also true on Windows).  This is not to say that such
a facility shouldn't exist in the standard libraries, but that filepath
isn't really the place for it.
