large exit values (>255)

[Mike Frysinger]

seems there's a way to get bash to report exit values greater than 255 ...

since it requires certain key presses, things in between <...> means a key 
press rather than typing literally ...

$ true
$ echo '<enter>
<ctrl+c>
$ echo $?
128
$ echo '<enter>
<ctrl+c>
$ echo '<enter>
<ctrl+c>
$ echo $?
128

$ true
$ echo '<enter>
<ctrl+d>
$ echo $?
258

$ true
$ echo '<enter>
<ctrl+d>
$ echo '<enter>
<ctrl+c>
$ echo $?
386

that doesnt seem right to me :)

the first test seems fine, and older versions of bash would set 258 for the 
second test (not sure if it's correct though), but the third test looks like a 
regression (not clearing exit status completely somewhere ?).
