From: Brandon Casey <drafnel@xxxxxxxxx>
The /usr/xpg4/bin/sh shell on Solaris only executes a trap handler set
within a function from the first-level function call made from within the
function that set the trap. In other words, if func1 sets a trap, then
calls func2 which triggers the trap, then the trap handler will be executed
correctly. If instead of exiting, func2 calls func3, and func3 satisfies
the conditions for triggering the trap, the trap handler will NOT be
executed.
This trap sequence exists in git-bisect.sh and is exercised by tests
t6030.12 and t6030.13 which fail when the /usr/xpg4/bin/sh shell is used.
Add a test that will fail sooner and more precisely than the t6030 tests.
