+# zfcd:  change directory on the remote server.
+#
+#  Currently has the following features:
+# --- an initial string matching $HOME in the directory is turned back into ~
+#     to be re-interpreted by the remote server.
+# --- zfcd with no arguments changes directory to '~'
+# --- `zfcd old new' and `zfcd -' work analagously to cd
+# --- if the connection is not currently open, it will try to
+#     re-open it with the stored parameters as set by zfopen.
+#     If the connection timed out, however, it won't know until
+#     too late.  In that case, just try the same zfcd command again
+#     (but now `zfcd -' and `zfcd old new' won't work).
+
+# hack: if directory begins with $HOME, turn it back into ~
+# there are two reasons for this:
+#   first, a ~ on the command line gets expanded even with noglob.
+#     (I suppose this is correct, but I wouldn't like to swear to it.)
+#   second, we can no do 'zfcd $PWD' and the like, and that will
+#     work just as long as the directory structures under the home match.
