strjoin change ramifications with escape sequence behavior

[Daniel J Sebald]

Stefan,

I see a recent mod in the source tree for the script strjoin.m.  Could 
you please look at this again and consider if your change alters the 
behavior of the routine?  I'm not sure what the routine is supposed to 
do exactly, but I'm just noting that sprintf() has varied behavior for 
the way "escape" sequences are handled.  For example:

Before change:

> > strjoin({"Octave","Scilab"}, "\n")
ans = Octave
Scilab

After change:

> > strjoin({"Octave","Scilab"}, "\n")
ans = Octave


John, perhaps you could look this one over as well.  I'm just curious 
why inside the Octave script displaying [cstr(:).'; delimiter(:).']{:} 
results in the following:

ans = Octave
ans =

ans = Scilab
ans =

while the return value after Stefan's change shows only the first 
portion of that result.  I guess a routine can't return multiple answers.
