invalid strings with IO.pipe and readline

[macosforge@…]

Test case:

#!/usr/local/bin/macruby

r, w = IO.pipe
w.write("test\r\n")
l = r.readline("\r\n")

puts l.chomp("\r\n").inspect # ruby1.9: "test", macruby: "test\r\n"

puts l.match("e")[0].inspect # ruby1.9: "e", macruby: " "

Calling readline on an IO.pipe stream with a delimiter causes really odd strings to be returned, they don't behave correctly in a number of cases including the two shown. Possibly an encoding issue?

Seems to be fixed in trunk.

$ ./miniruby  t.rb 
"test"
"e"
$ ruby19  t.rb 
"test"
"e"
