[bug] two bugs: one with comments and with exporting inline tasks

Hello,

I have run into two problems.  The first is one which has existed for a long time as
is somewhat minor: a line consisting of just #+ will be treated as part
of the text.  The regex for comments requires a space but it would be
nice if this weren't required.

The second problem is more serious: exporting to latex when there are
inline tasks does not work.  I believe the problem is due to a
combination of headings being treated as list entries and the
introduction of the new list handling code.

Please see attached files for a full example (org, tex and pdf) and
which includes the version information (org up-to-date as of an hour ago
basically).

Thanks,
eric

* problem exporting to latex with inline tasks
I often use inline tasks to help me organise my thoughts as I am
writing long documents.  However, exporting these no longer seems to
work.
***************************** TODO figure out why this doesn't work
***************************** END

There are two problems with exporting inline tasks:

1. If the whole document is exported, the inline task headline text is
   inserted into the =[ ]= optional argument for an =\item=, generating
   something like this:

   : \item[@<span class="todo TODO"> TODO figure out why this doesn't work]

   Further, this text in the =[]= appears in subsequent items as well!
   See the attached =pdf= document.

2. If only the current subtree is exported, the exported latex ends
   just before the inline task.


I believe both of these problems are related to the new list handling
as I used to be able to export inline tasks perfectly fine in
September.

  This is some text that should appear normally.  The next few lines are
  a comment which should not be exported.
\textbf{Immediately} before this sentence is the appearance of \verb=#+= which should
not be there.  I believe the regex requires a space after the plus
sign but maybe a check for end of line \verb=$= as an alternative to a space
could be used?  I.e. something like \verb=#\+\( |$\)= although I don't know if
that type of expression will work\ldots{}
