Using symlinks to folders causes other problems too.
For instance, if use the MH rmf command to remove a symbolic link to a
folder (on MH 6.7.2 and 6.8.3, at least), rmf will not remove the
symlink. Instead, if it can, rmf will remove all messages from the
folder that the link points to. Some people might not expect this.
A symlink within an MH folder tree causes wrong message counts in
"folder -total" too.
If MH is changed to allow the fast folder hacks, it might be a good
idea to patch rmf and other places affected by symlinks.
