Several functions that create or rename their files now treat their
|
||||||
|
destination specially if it happens to be a directory, even when its
|
||||||
|
name does not appear to be that of a directory. For example,
|
||||||
|
@code{(rename-file "A" "B")} no longer renames @file{A} to @file{B} if
|
||||||
|
@file{B} happens to be a directory. This is so that dealing with
|

files becomes more of an adventure.
