UNABLE TO PARSE THE WIKI PAGE. ERROR WAS: NO LEXER FOR ALIAS U'LANG' FOUND

Issue #4589 resolved

There is an issue where wikis containing unrecognized lexer specifications with the notation

{{{ #!language }}}

aren't rendered at all. This can be worked around by providing a language from http://pygments.org/docs/lexers/#lexers-for-agile-languages in the short names. This should fail more gracefully.
