Bug#687450: checkbashisms: please add bounds check for "exit"

[Thorsten Glaser]

Package: devscripts
Version: 2.12.2
Severity: wishlist

Hi,

please add a check to checkbashisms that "exit" has exactly
0 or 1 argument and, if it has one, it's a number between 0
and 255 inclusive. Note that "exit" doesn't support "--" as
argument separator portably either, and "exit -1" has never
been portable.
