\w should turn the leading part of the prompt into ~ if it matches the
user's home directory; I think I know that it /homes/neat/car/lamy by now.

also, I would like a tcsh-like option to display only the base name of the
current directory (I hate starting to type at column 40 :-)

Finally, I think ksh allows for commands to be executed within the prompt,
something like PS1='`basename \w`' would be cute :-)

Here is my addition to the decode_prompt_string().
I have added \W which inserts the trailing component of cwd.
It's like %c or %. in tcsh.
I.E. PWD=/usr/foo/bar
\W -> "bar"

You need to apply Anders Ellefsrud's patch for \~ before you can
apply mine.
