There are a few remaining compatability issues with addpath/rmpath.  There are 
also a number of suggestions I have for the behavior of these functions.   I 
have made fixes and changes against a recent octave-forge version and before 
I apply them and send in the diffs against the latest in the Octave CVS, I 
would like some feedback on whether the changes are wanted.

The issues are:

octave:1> addpath('/tmp');addpath('/tmp/');path

adds /tmp and /tmp/ to the path.  This is both a compatability and an 
unexpected behavior issue.  (Perhaps it is not too unexpected beause tcsh 
allows it.  However, tcsh allows multiple instances of the same directory in 
the path environment variable which neither Octave nor Matlab do.).  

Also, you will notice that '.' gets pushed down in the path list.  This is a 
problem that caught me a few times.  Matlab always has '.' first in the path 
list (and it is not listed by when "path" is invoked, but I think it is 
better to list it).

Also, I suggest a warning about incompatable behavior when the (extremely 
useful) "//" syntax is used.
