style for error and warning messages

[John W. Eaton]

Currently, most of Octave uses a style for error and warning messages 
that is something like this:

  warning ("nchoosek: possible loss of precision");

but now that error and warning messages display stack trace information 
by default, having the name of the function as a prefix for the message 
is redundant.  Does anyone object to removing the function name as a 
prefix to error and warning messages?
