DocBook XML is superficially compatible with DocBook SGML but has a
slightly stricter DTD that we have been violating in a few cases.
Although XSLT doesn't care whether the document is valid, the style
sheets don't necessarily process invalid documents correctly, so we need
to work toward fixing this.
This first commit moves the indexterms in refentry elements to an
allowed position. It has no impact on the output.
Before, some places didn't document the short options (-? and -V),
some documented both, some documented nothing, and they were listed in
various orders. Now this is hopefully more consistent and complete.
Create separate appendixes for contrib extensions and other server
plugins on the one hand, and utility programs on the other. Recast
the documentation of the latter as refentries, so that man pages are
generated.
Instead of just stopping after removing an arbitrary subset of orphaned
large objects, commit and start a new transaction after each -l objects.
This is just as effective as the original patch at limiting the number of
locks used, and it doesn't require doing the OID collection process
repeatedly to get everything. Since the option no longer changes the
fundamental behavior of vacuumlo, and it avoids a known server-side
limitation, enable it by default (with a default limit of 1000 LOs per
transaction).
In passing, be more careful about properly quoting the names of tables
and fields, and do some other cosmetic cleanup.
Also, handle failure better: don't just blindly keep trying to delete
stuff after the transaction has already failed.
Tim Lewis, reviewed by Josh Kupershmidt, with further hacking by me.
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.
