H A Doptions.hdiff 223281 Sat Jun 18 21:57:03 MDT 2011 jilles sh: Add do-nothing -h option.

POSIX requires a -h option to sh and set, to locate and remember utilities
invoked by functions as they are defined. Given that this
locate-and-remember process is optional elsewhere, it seems safe enough to
make this option do nothing.

POSIX does not specify a long name for this option. Follow ksh in calling it
"trackall".
