/*
 * txbox.c - custom window bordering routine for ncurses windows.
 *
 * Copyright (c) Gerard Paul Java 2002
 *
 * This function is written to address a strange symptom in ncurses 5.2, at
 *least on RedHat 7.3.  The border drawn by the box() macro (actually an alias
 * for a call to wborder()) no longer uses the color attributes set by
 * wattrset(). However, the addch() and wvline() functions still do.
 *
 * The tx_box function is a drop-in replacement for box().
