Sorry, here's the attachment.
I wasn't fully aware of the procedures. I'm reading the contributor's
guide now...


Did I get everything right this time?

- I create a new block with some HTML in it.
- I configure the block, setting Visibility to "Show on only the listed
pages." and list just "<front>".
- I save and get the following warning: 


warning: preg_match() [function.preg-match]: Unknown modifier '3' in
/home/www/site/modules/block.module on line 474.


The block does not show up on the front page.

Here's a patch. preg_quote(variable_get('site_frontpage', 'node'), '/')
did the trick:
