calendar -a failing in 10.2-RELEASE

[Robert Ames]

In 10.2-RELEASE running "calendar -a" as root fails when user calendar files have a #include line.  This worked in 10.0-RELEASE (and before).  From my limited testing I think it's looking for the included files relative to root's home directory and not the user's home directory.  The svn repository shows some changes in this area in recent releases.  Not sure if this new behavior is intentional.
