vtrek

howard at cyb.eng.UUCP
suggests using "tputs(tgoto...))" rather than "fputs(tgoto...)"
in vtrek.
This is necessary to deal with padding correctly,
BUT a vt100 still gets 'J's and no proper cursor positioning,
as several people have reported.

Reason: insufficient buffer space allocated to the termcap "cl" string
(which therefore overwrites "cm" - with a 'J') when calling "tgetstr" in
termio.c:terminit function.

Minimal Fix:
in file termio.c, change declaration "char cl[5];" to "char cl[10];".

(The better fix is to use the "char **" parameter to "tgetent" to assist you
in allocating space to each entry, as much as it actually needs out of a larger
array, along the lines of

	char * cl, *cm;    /* terminal control strings */
	char tentries[100];	/* storage area for terminal controls */
	...
	p = tentries;

	cl = p;
	tgetstr("cl", &p);
	cm = p;
	tgetstr("cm", &p);
