H A Dhistedit.c685a2705 Wed Dec 29 19:39:51 GMT 2010 Jilles Tjoelker <jilles@FreeBSD.org> sh: Properly restore exception handler in fc.

If SIGINT arrived at exactly the right moment (unlikely), an exception
handler in a no longer active stack frame would be called.

Because the old handler was not used in the normal path, clang thought it
was a dead value and if an exception happened it would longjmp() to garbage.
This caused builtins/fc1.0 to fail if histedit.c was compiled with clang.
