@code{buffer-file-truename} of all visited files when deciding whether a
given file is already in a buffer, instead of just
@code{buffer-file-name}. If you attempt to visit another file which is
-a hard-link or symbolic-link to a file that is already in a buffer, the
-existing buffer will be found instead of a newly created one.
+a symbolic link to a file that is already in a buffer, the existing
+buffer will be found instead of a newly created one. This works if any
+component of the pathname (including a non-terminal component) is a
+symbolic link as well, but doesn't work with hard links (nothing does).
@cindex creating files
If you want to create a file, just visit it. Emacs prints
that newly made backup is included in the count in @code{kept-new-versions}.
By default, both variables are 2.
-@vindex trim-versions-without-asking
- If @code{trim-versions-without-asking} is non-@code{nil}, excess
+@vindex delete-old-versions
+ If @code{delete-old-versions} is non-@code{nil}, excess
middle versions are deleted without notification. If it is @code{nil}, the
default, you are asked whether the excess middle versions should
really be deleted.
