\include is special-cased in the lexer in order to accept
\stringidentifier.  Previously $xxx in #{ ... #} was translated into
\something artificially.  This translation is no longer happening.  But
\include does not know what to do with $ yet.

Expect a fix in the next days.  Thanks for the report, and sorry for the
oversight.
