   Sometimes, a directory is ordinarily accessed through a symbolic
-link, and you may want Emacs to preferentially display its ``linked''
-name instead of its truename.  To do this, customize the variable
-@code{directory-abbrev-alist}.  Each element in this list should have
-the form @code{(@var{from} . @var{to})}, which says to replace
-@var{from} with @var{to} when it appears in a directory name.  For
-this feature to work properly, @var{from} and @var{to} should point to
-the same file.  The @var{from} string is actually a regular expression
-(@pxref{Regexps}); it should always start with @samp{\`}, to avoid
-matching to an incorrect part of the original directory name.  The
-@var{to} string should be an ordinary absolute directory name.  Do not
