let it handle proper parsing and handling of arguments. Fixes
issue most recently raised by Linda Walsh <bash@tlinx.org>.
Reverses change from 9/11/2008 (see above)

----
doc/{bash.1,bashref.texi}
- clean up `set -e' language to make it clearer that any failure of
a compound command will cause the shell to exit, not just subshells
and brace commands
8/17
----
configure.in
- make the various XXX_FOR_BUILD variables `precious' to autoconf to
avoid stale data
- change how CC_FOR_BUILD is initialized when cross-compiling and not,
but do not change behavior
- initialize CFLAGS_FOR_BUILD to -g when cross-compiling
- initialize LIBS_FOR_BUILD to $(LIBS) when not cross-compiling, empty
when cross-compiling
- create AUTO_CFLAGS variable to hold basic CFLAGS defaults; used when
CFLAGS not inherited from environment (like effect of old
auto_cflags variable)
- substitute LIBS_FOR_BUILD into output Makefiles
[changes inspired by bug report from Nathan Phillip Brink
<ohnobinki@ohnopublishing.net> -- gentoo bug 378941]
builtins/Makefile.in
- substitute LIBS_FOR_BUILD from configure, not strictly initialized
to $(LIBS)
