Hi Bernt,

I've checked in a slightly different version[1] of this fix. Thanks for
the report; it wasn't nice to have been throwing errors every time an
unrecognised (e.g. partial) language string was entered, even if most of
the time font-lock was subduing these errors.

Footnotes:
[1] I've made the org-src fontification function test, early on, whether
the language major-mode function exists. If it doesn't then it returns
immediately.
