I found that the word links filter would break and give an error if there's a forward slash (/) in one of the word_link words. This is because the forward slash is being used as a delimiter in word_link_convert_text().

Warning: preg_match_all(): Unknown modifier '[some letter]' in word_link_convert_text()...

I fixed this by adding a character to escape forward slashes before the pattern is fully built.

Thank you for your patch.
I think that specifying delimiter to preg_quote() function is better way, isn't it?
