 AFAIK, there isn't such thing - only a system-wide default.

 Maybe, but it's really unclear what colour we want the bikeshed
 Judging by the lengthy discussion on developers@, and strong
 objections by some developers to things like certain editing modes,
 I'm extremely reluctant to modify any defaults.

 My understanding when making the change was that ~/.profile
 is only for sh(1) type shells, and the Xsession file is executed
 in sh(1) through the shebang, and any alternative shell will be
 spawned later.
 I'm not sure about tcsh - 
 csh(1) seems to use these files rather than .profile:
      ~/.cshrc     Read at beginning of execution by each shell.
      ~/.login     Read by login shell, after `.cshrc' at login.
      ~/.logout    Read by login shell, at logout.
 The default ~/.cshrc on NetBSD will specify a path, so you'll
 get the right thing regardless of xdm or login shell.
