Re: user-homedir-pathname not amenable to merging.

The fix is in CVS, and I don't think that anything broke in the process.
The function that was setting name/and type to :UNSPECIFIED is called
by a few other functions (including ENSURE-DIRECTORIES-EXIST), so the
results in those cases would have had the same difficulies with
subsequent attempts to involve them in  MERGE-PATHNAMES calls.
