Subject: * tests/tcltest.test: * doc/tcltest.n: *
 library/tcltest1.0/tcltest.tcl: Removed the extra return at the   end of the
 tcltest.tcl file.

  Applied patches sent in by Andreas Kupries to add helper procs for
  debug output, add 3 new flags (-testsdir, -load, -loadfile), and
  internally refactors common code for dealing with paths into
  separate procedures. [Bug: 2838, 2842]
