      exp/template/html: elide comments in template source. · 35819729
      Mike Samuel authored 
      When templates are stored in external files, developers often embed
comments to explain&|disable code.

  <!-- Oblique reference to project code name here -->
  {{if .C}}...{{else}}<!-- commented out default -->{{end}}

This unnecessarily increases the size of shipped HTML and can leak
information.

This change elides all comments of the following types:
1. <!-- ... --> comments found in source.
2. /*...*/ and // comments found in <script> elements.
3. /*...*/ and // comments found in <style> elements.

It does not elide /*...*/ or // comments found in HTML attributes:
4. <button onclick="/*...*/">
5. <div style="/*...*/">

I can find no examples of comments in attributes in Closure Templates
code and doing so would require keeping track of character positions
post decode in

  <button onclick="/&#42;...*/">

To prevent token joining, /*comments*/ are JS and CSS comments are
replaced with a whitespace char.
HTML comments are not, but to prevent token joining we could try to
detect cases like
   <<!---->b>
   </<!---->b>
which has a well defined meaning in HTML but will cause a validator
to barf.  This is difficult, and this is a very minor case.
I have punted for now, but if we need to address this case, the best
way would be to normalize '<' in stateText to '&lt;' consistently.

The whitespace to replace a JS /*comment*/ with depends on whether
there is an embedded line terminator since
    break/*
    */foo
    ...
is equivalent to
    break;
    foo
    ...
while
    break/**/foo
    ...
is equivalent to
    break foo;
    ...

Comment eliding can interfere with IE conditional comments.
http://en.wikipedia.org/wiki/Conditional_comment

<!--[if IE 6]>
<p>You are using Internet Explorer 6.</p>
<![endif]-->

/*@cc_on
  document.write("You are using IE4 or higher");
@*/

I have not encountered these in production template code, and
the typed content change in CL 4962067 provides an escape-hatch
if conditional comments are needed.

      exp/template/html: simplify transition functions · 1f577d26
      Mike Samuel authored 
      This simplifies transition functions to make it easier to reliably
elide comments in a later CL.

Before:
- transition functions are responsible for detecting special end tags.
After:
- the code to detect special end tags is done in one place.

We were relying on end tags being skipped which meant we were
not noticing comments inside script/style elements that contain no
substitutions.
This change means we will notice all such comments where necessary,
but stripTags will notice none since it does not need to.  This speeds
up stripTags.
