Return to cmd-show-window-options.c CVS log

Up to [local] / src / usr.bin / tmux

Eliminate duplicate code and ease the passage for server-wide options by adding
a -w flag to set-option and show-options and making setw and showw aliases to
set -w and show -w.

Note: setw and showw are still there, but now aliases for set -w and show -w.
