 indicate the default file should be read at that point.  This allows
 effects like the following:
 
-example(zstyle recent-dirs-file ':chpwd:*' \

 Recent directories are read from a file numbered according to
 the terminal.  If there are insufficient entries the list
 is supplemented from the default file.

+It is possible to use tt(zstyle -e) to make the directory configurable
+at run time:

+example(zstyle -e ':chpwd:*' recent-dirs-file pick-recent-dirs-file

+    reply=(~/.chpwd-recent-dirs-writing)
+  else

+In this example, if the current directory is tt(~/text/writing) or a
+directory under it, then use a special file for saving recent
+directories, else use the default.
