Subject: emacs' ruby-mode, irb and line numbers

Hello,

I'm using Emacs' ruby-mode together with irb as inferior ruby, but the
line numbers for exceptions end up completely wrong:

irb(main):1495:0> t = Ribbit::TargetFactory.new(1, :snmp, 'ti100710a080')
"ti100710a080"
ArgumentError: mandatory argument "specifier_id" missing
	from (irb):1459:in `initialize'
	from (irb):1472:in `new'
	from (irb):1472:in `initialize'
	from (irb):1495:in `new'
	from (irb):1495
irb(main):1496:0> 

The line numbers reported by irb are in this case about 1200 lines too
big.

Actually, this is caused by two unrelated problems:

- Line numbers are not adjusted in irb before it evaluates a chunk of
  Ruby code, causing the source references to be wrong.
- C-c C-e causes irb to print a bunch of prompts, one for each source
  line) causing the line number counter to increment repidly.

I have spent the previous 30-40 minutes searching web and docs, but at
no avail. I would be very grateful if anyone could provide a solution
to these problems.

Thanks in advance!
