Doc: hack on table 26.1 till it fits in PDF format.
I abbreviated the heck out of the column headings, and made a few
small wording changes, to get it to build warning-free. I can't
say that the result is pretty, but it's probably better than
removing this table entirely.
As of this commit, we have zero "exceed the available area" warnings
in a US-letter PDF build, and one such warning (about an 863-millipoint
overrun) in an A4 build. I expect to get rid of that one by renaming
wait events, so I'm not doing anything about it at the formatting
level.
