PATCH: description of PATH_DIRS option.

[Peter Stephenson <pws@xxxxxxx>]

While waiting to see if a test fell over, I started writing some more
option tests and fell over this, which looks like it needs documenting,
though I assume it's always been like that.

I suppose it's like this since other shells expect command searches to work
like this.

I intend to commit this to the 4.0 branch, too.
