The theme system is very inconsistent and not clean. In a steady stream
of patches i'll try to make the theme system clean and let most of the
theme functions behave the same..

One of the main goals is, that when writing themes in PHPTemplate for
example, the way how things are being returned is different from theme
function to theme function..

Let's try to unify this, so theming will be more efficient, simpler and
more consistent..

The attached patch does:
- remove unused function theme_help() and theme_error();
- added a wrapper function drupal_get_help() inside common.inc (for
consistency with drupal_get_title(), drupal_get_breadcrumb(), etc);
- reimplemented theme_help(), only this time for a more consistent way
for themers;

This patch makes it easier to theme the page specific helptexts for

To change your PHP-based themes, you can do:

-  if ($help = menu_get_active_help()) {
-    $output .= '<small>'. $help .'</small><hr />';
-  }
+  $output .= theme('help', drupal_get_help());

To change your PHP-Template based theme:

 if ($help): 

 print $help; 


becomes a simple:

 print $help; 

If this patch is accepted i'll try to make the functions for returning
the local tasks and the status messages behave the same..

Overriding the <div class="help">...</div> could be done through
deifinig your own theme_help() function in your theme or template.php

+1 from me
it makes help text themeable
it uses semantic markup, which is good practice, or as some say the
Right Way

The patch had DOS line endings and wouldn't apply.

I fully support this patch. +1

Because Adrian +1's this, his reward is a proper patch against
PHPTemplate, sorry I forgot this one...
here it is, a really simple one liner which does the job...
