[Orgmode] additional bugs in latex export

[John Rakestraw]

Hi --

I'm starting to use latex export more, and noticed three problems
related to tables:

  - If the first column in a table has an inactive time stamp, then
    strange things happen -- in various tests, I've seen only
    seemingly random cells from a long table exported, or sometimes
    only the header row (that doesn't have the time stamp in it) and
    no other rows exported.
  - If the text in the first column begins with a left bracket, then
    the first cell in each row is blank.
  - If a table is long enough that it should continue on a following
    page, there's no page break -- instead, lines continue into the
    bottom margin. What fits on that page prints, but nothing else
    prints. If I break the table at the bottom of the page with an
    empty line, the rest of the table continues as expected on the
    following page.
