Improve markup, particularly of the table of functions; add or improve
examples for some of the functions; wordsmith some of the function
descriptions.
Commit 33bd250f6c could have done with
some more review:
Adjust coding so that compilers unfamiliar with elog/ereport don't complain
about uninitialized values.
Fix misuse of PG_GETARG_INT16 to retrieve arguments declared as "integer"
at the SQL level. (This was evidently copied from cube_ll_coord and
cube_ur_coord, but those were wrong too.)
Fix non-style-guide-conforming error messages.
Fix underparenthesized if statements, which pgindent would have made a
hash of, and remove some unnecessary parens elsewhere.
Run pgindent over new code.
Revise documentation: repeated accretion of more operators without any
rethinking of the text already there had left things in a bit of a mess.
Merge all the cube operators into one table and adjust surrounding text
appropriately.

Introduce distance operators over cubes:
<#> taxicab distance
<-> euclidean distance
<=> chebyshev distance
Also add kNN support of those distances in GiST opclass.

With the arrival of the CUBE key word/feature, the index entries for the
cube extension and the CUBE feature were collapsed into one. Tweak the
entry for the cube extension so they are separate entries.
Block elements with verbatim formatting (literallayout, programlisting,
screen, synopsis) should be aligned at column 0 independent of the surrounding
SGML, because whitespace is significant, and indenting them creates erratic
whitespace in the output. The CSS stylesheets already take care of indenting
the output.
Assorted markup improvements to go along with it.
