Ah, it's slightly more subtle.  Notmuch correctly uses stat() instead of
lstat() to check whether the link target changed.  However, mtime for
your mail root directory (containing the symlinks) does not get updated
when the target of the symlinks is updated.  I think the only way to fix
this is to replace the current search (which skips a directory as soon
as it's mtime is older than the database) with one that enters all
directories so that symlinks are actually followed.
