Bug: 3 bugs and 2 proposals on ascii/html export [7.8.03]

[Mathias Bauer <mbauer@gmx.org>]

Hi!

I just played with org's export functionality and following
minimal org file.  This results in three minor bugs and two
proposals/questions on org's behavior.

-------------------- file1.org --------------------
#+STARTUP: showeverything
#+OPTIONS: author:nil email:nil timestamp:nil
* Some section
Some text.
* TODO Some section with a TODO keyword
Some text.
* DONE Some section with another TODO keyword
Some text.
* Some section with TAG at the end                           :some_tag:
Some text.
* TODO Some section with TODO keyword and TAG at the end  :another_tag:
Some text.
---------------------------------------------------

* ASCII/Latin-1/UTF-8 export

** Bug 1: Underlining the headlines

Headlines without tags are underlined in a wrong manner.  It's
one character too long.

** Question/Proposal

As default, all level 1 headlines are underlined by - characters
and level 2 headlines with =.  Wouldn't it be more logical the
other way round: the lower the level, the more important the
headline and hence the "bigger" its underlining?  (Of course the
user can change the variable org-export-ascii-underline.)

* HTML export

** Question/Proposal

----------snip----------
<h2>...Some section with TAG at the end &nbsp;&nbsp;&nbsp;<span class="tag"><span class="some_tag">some_tag...
----------snip----------

Isn't a single space enough for separating the heading's text and
the tag?  Beside their number, the additional three (why not five
or n?) "&nbsp;" seem a little bit freaky to me...

To keep things even more flexible, couldn't the blank and the
"&nbsp;" be skipped both and could the CSS "tag" class be
modified instead.  Unfortunately, I don't know enough of CSS yet
to check if that will be possible at all.

For the table of contents we will have a similar phenomenon if an
additional "#+OPTIONS: tags:t" is added.  The separation between
text and tag in this case consists of three "&nbsp;" and *no*
space before.

** Bug 2: Exporting the tag into the toc

Adding "#+OPTIONS: tags:t" results in the following exported toc:

----------snip----------
<li>...Some section with TAG at the end&nbsp;&nbsp;&nbsp;<span class="tag"> some_tag</span></a></li>
----------snip----------

There is a space inside the <span>...</span> just before the tag
name which should not be there.

** Bug 3: Exporting the TODO keywords

----------snip----------
<h2>...<span class="todo TODO"> TODO</span> Some section with a TODO keyword</h2>
----------snip----------

There is a space inside the <span>...</span> just before the TODO
keyword which should not be there.


Could you please consider fixing these bugs.  Thanks for this
wonderful piece of software :-)

P.S. For proving the above topics I used the proposed minimal org
installation.  So nothing in the following settings report has
something to do with my personal configuration.  But if it's the
will of (org-submit-bug-report)... :-)
