      issue #1: twm random window placement handles large windows poorly
      eliminate a fixed-size buffer in Execute() function.
      use Debian's package-files as starting point for test-packages
      updated patch to work with code, reflect a change made in 2016...
      adapted/updated patch from Debian #956434
      adapted/updated patch from Debian #956434
      eliminate some unnecessary(?) goto statements
      add "-V" version-message
      allow most options to be long/abbreviatable for consistency,
      remove clutter not needed with Xorg
      fix the cppcheck style- and format-warnings
      add/use functions to make warning messages more consistently use the \ 
program name as a prefix
      use new warning-message functions in the remaining places where suitable,
      make the "-V" version print less cluttered (and more like most \ 
programs)
      add/use new function parseWarning, which honors -v/-q options
      indent lex/yacc files using xxx-indent (twm-indent uses GNU indent, which
      include twm.h in header files which rely upon its definitions
      X11R5 change lost the update for yylineno needed to make parse messages
      mention newer behavior of -q/-v options
      issue #8: twm displays all windows as "Untitled"
      quiet a misleading warning in grammar
