Hi folks, thanks for the useful code!

I've added some functionality to PHP Markdown Extra and PHP
SmartyPants. Diffs attached.

For PHP Markdown Extra:

*A new config option, MARKDOWN_HEADER_BASE, which sets the largest
header level that Markdown can generate and defaults to 1; useful if
you use <h1> for site-wide elements and want Markdown-generated
headers to start at <h2>. It will use <h6> instead of trying to
generate <h7>, <h8>, &c.

*A new config option, MARKDOWN_STRIP_UNRESOLVED_FNS, which will cause
unresolved footnote references to be stripped instead of left in the
output text uninterpreted and defaults to false; useful when Markdown
is being run over post excerpts or if you use features like <!-- more
--> to only show part of the post on the front page.

For Smartypants:

*1/4, 1/2, and 3/4 will be replaced with fraction entities.
