Even /bin/sh (which is unfit for git consumption) on Solaris 7 produces
non-zero for all three tests:

   status is 255
   status is 255
   status is 255

I set SHELL_PATH=/usr/xpg4/bin/sh aka ksh when compiling git which also
handles your test correctly:

   status is 1
   status is 1
   status is 1

IRIX6.5 /bin/sh and /bin/ksh produce the correct results also.
