Very minor feature suggestion

It might be nice for psql to have a 'htmlcaption' boolean pset option that would wrap the provided title/caption, if any, in a caption tag in the HTML report output, when using html format.

Motivation:

When I use:

\pset title 'Some title'

or

\C 'Some title'

psql emits the text:

Title is "Some title".

even when using html format. This seems more like a diagnostic/annotation (like 'Title is unset', which is what you get from a plain "\pset title") than report output. For casual use, even "\echo Some title" is more pleasant, except for post-processing by scripts, which people are no doubt doing. When using html format, it would arguably be better for the title to be wrapped in a caption tag inside the table itself. You couldn't change the default behavior, but the html caption would be a nice option.
