Doc: hack table 13.2 "Conflicting Lock Modes" till it fits in PDF.
I can't see any way to make this table fit in PDF column width without either a fundamental redesign or abbreviating EXCLUSIVE. So I did the latter. It'd be nicer if the abbreviating didn't leak into the HTML output as well; but the hackery required to make the output different seems like more trouble than it's really worth.
