 The syntax is unimplemented -- you can only select a section, optionally 
followed by a flags, like with the .section directive.  The reason code 
disagrees with documentation is probably them having been added at 
different times, about a year apart.  A possible workaround is as follows:

	.section sec1

	.pushsection sec2
	.pushsection sec2
	.subsection 1
	.previous
	.popsection

Ugly, but it should work.  I think it would be a good idea to make 
.pushsection match the documentation with respect to subsections though as 
this is useful semantics.
