The lexer breaks on some specific inline html

[jorissteyn]

See test case and description in lexer.el:

;; This test case is a simplified version of Zend_Gdata_Docs, for some
;; reason the lexer chokes on the html contents. The combination of
;; the first #header, together with the dot in 2.4em triggers the
;; error.
;;
;; Tips for debugging this:
;;  * put breakpoints in semantic-php-wy.el
;;  * or add debug statements to lexical analyzers in semantic-php.wy
;;  * inspect the end position of emitted inline_html tokens
;;  * perhaps the order of the analyzers in semantic-php-wy-lexer is wrong
