doc/: Align layout control commands to right margin in `tabbing' etc.
This is mostly clean in `--word-diff'. Here are the exceptions.
* doc/parsing.tex: `--word-diff' gets confused around the various
`condition-with-location' subclasses. This is clean in `-b', so
there's not actually anything complicated happening here.
* doc/parsing.tex: I've sneakily removed a pointless trailing `%'.
* doc/runtime.tex: I've inserted a couple of linebreaks with `%' so as
to shorten the source-file lines.
* doc/runtime.tex: Some `\-' have harmlessly moved past `@\\' macro-
backslashes to take their proper places on the right margin.
