jove 4.9 (support for TVI FUNCT key)

[Rob McMahon]

Televideo terminals and some others (e.g. the Newbury's round here) have a
FUNCT key which sends `^Ax\r' if held down while pressing `x'.  This little
function allows you to use this as a meta-key if you bind tvi-function-key to
C-a.  (Of course you'll want to bind beginning-of-line somewhere else, like
ESC C-a.)
