Fix for PR#1287. This makes sh behave sensibly in case statements in the

face of aliases.  Note, bash doesn't do aliases while running scripts, but
"real" ksh does..

Also:
  Reduce redundant .Nm macros in (unused) bltin/echo.1
  nuke error2, it's hardly used.
  More -Wall cleanups
  dont do certain history operations if NO_HISTORY defined
  handle quad_t's from resource limits
