tweak for compat with broken /bin/sh on AIX ibm.risc

Browse source 
AIX on ibm.risc comes with a broken version of ksh88 as /bin/sh
where the following causes breakage in the parser (spurious syntax
errors):

	(set -o posix) 2>/dev/null && set -o posix

However, prefixing it with 'command' (while keeping the subshell)
circumvents the problem. So, why not.

	(command set -o posix) 2>/dev/null && set -o posix
