dispatch: exit with 8-bit exit code
The exit code returned from a program to the shell is unsigned 8-bit, but
Mercurial would sometimes try to exit with negative numbers or None. sys.exit
on Unix will convert that to 8-bit exit codes, but on Windows negative values
showed up as 0.
The exit code is now explicitly converted to unsigned 8-bit.
