/*
* NOTE:
* On Linux console, the 'me' termcap setting \E[m resets _all_ attributes,
* including color. However, if we use 'se' instead, it doesn't clear the
* boldface. To compensate, we reset the colors when we put out any "ending"
* sequence, such as 'me'.
*
* In rxvt (2.12), setting _any_ attribute seems to clobber the color settings.
