I think your patch is also OK.

I'm not sure what to suggest for the best scripting language
equivalent for find_last_of.  A regular expression?  That doesn't seem
like a great solution and would be a bit messy in the current case
because \ is special in a regular expression.  For example, you need
something like

  regexp ('/foo/bar\baz', '[\\/][^\\/]*$')

Do we need a new function, or can someone think of a good way to do
this with functions we currently have?
