>Description:

If you look in termcap (4.x and/or 5.x - it seems that it is everywhere)
around xterm-ic record, you see:

# comment \
xterm-ic ... \
	...

Unfortunatelly, cap_mkdb (specifically cgetnext() from libc) interprets
it just as one big comment, because "\" has bigger priority that "#", so
"\" is applied before "#". It means that xterm-ic is not compiled into
termcap.db database.

>How-To-Repeat:
>Fix:

The first variant: Just remove "\" from the end of comment line:

Or the third possible fix - change the logic in
src/lib/libc/gen/getcap.c. I do not know if it is
a bug, or a feature :o)
