[I posted a response to this a few days ago via Google, but it hasn't shown
up yet so I'm reposting].

It is, but unfortunately at least one of the special characters (^C) appears
to be ignored completely now.  With or without a .inputrc, on both Tru64
and Solaris 2.8 (sparcv9, LP64) I can't get bash 3.0 to honor ^C.

On my Tru64 workstation, `stty -a' reports:

#2 disc;speed 38400 baud; 24 rows; 80 columns
erase = ^H; werase = ^W; kill = ^U; intr = ^C; quit = ^\; susp = ^Z
dsusp = <undef>; eof = ^D; eol = ^@; eol2 = ^@; stop = ^S; start = ^Q
lnext = ^V; discard = ^O; reprint = ^R; status = <undef>; time = 0
min = 1

bash-3.0 honors ^H, ^U, ^D, ^Z, but not ^C.  It just completely ignores it.
