I made a couple more places use stpcpy() in the code, optimizing away a
couple strlen() calls in the process.  I also tweaked the help code that
was abbreviating a long value using "..." to allow a string to fit if it
can, rather than always reserving space for the "..." chars.  I.e. if we
had room for 4 word chars, instead of outputting "w...", it would allow
a full "word" to be output, since it fits.
