[PATCH 3/3] [EXCEPTIONS] Eliminate global exerrno

[Jonathan Nieder <jrnieder@gmail.com>]

Pass the exit status from the exec builtin through the exitstatus
global.  This just eliminates a global variable; no noticeable
change is intended.

Based on v0.5.3~57 (Eliminated global exerrno, 2005-02-25).
