BUGS
If you call tgetstr to fetch ca or any other parameterized
- string, be aware that it will be returned in terminfo
- notation, not the older and not-quite-compatible termcap
- notation. This will not cause problems if all you do with
- it is call tgoto or tparm, which both expand terminfo-
- style strings as terminfo. (The tgoto function, if con-
- figured to support termcap, will check if the string is
- indeed terminfo-style by looking for "%p" parameters or
- "$<..>" delays, and invoke a termcap-style parser if the
