Patch to include -H in truss usage synopsis
If truss is run without arguments, it prints a short usage synopsis. This omits the -H option that was a relatively recent addition. Instead of
usage: truss [-cfaedDS] [-o file] [-s strsize] ...
It should say:
usage: truss [-cfaedDHS] [-o file] [-s strsize] ...
I have attached a patch for what it's worth.

truss: mention 'H' in usage
r295930 introduced the 'H' option to display thread IDs, but did not add
the option to usage().
