i've never used readline with any flavor of rc.  but i have
tried byron's rc as well as the p9p rc.  unfortunately,
it has nothing to do with rc — notice that ed has the same
problem.  readline actually fixes the problem.  bash works
fine.  er, scratch that.  bash works as expected.

i am experiencing the very same problem -- only i get
the echo every single time, not 2/3 -- and i get this
even when using pdksh.  as previously reported, bash (or
zsh, for that matter) does not suffer of this problem.
any help would be greatly appreciated.  the problem first
manifested itself after a system wide update... i'll see
if i can get a log of this and i will post it, if you
think this could be of help.

the only thing i can add is that the reason that bash
does not have this problem is because bash (readline) puts the console
into raw mode and so there is no accumulation of the input
and then the echo-off write of that input to the shell.

this smells like a synchronization problem, but if it is,
i missed it.

[9fans] p9p funny

[erik quanstrom]

i'm getting spurious echo in 9term on average about 2/3 of
the time.  this example sees the spurious echo every time.
programs like bash that eat cooked input don't seem to suffer
the same fate.

; flag v && echo true
flag v && echo true
; ed .rcrc
ed .rcrc
900
1
1
if (test -e /etc/rcrc)
q
q

has anyone else seen this?

It looks like you're you're using the Rakitzis rc; is readline involved?

Yes, on both OS X and Linux. I find I'm most likely to see it when
using non-p9p tools and setting cooked mode from the menu. Using p9p
tools via ssh also seems to trigger it. (i.e. open 9term, ssh to
another machine, and run 9 rc.)

  I actually thought it was a feature of cooked mode, I was quite
surprised to see it not manifest when I tested just now.
