"Streamlining" of Info directory headings

[Ulrich Mueller]

When entering Info in Emacs, on a system where both Emacs and XEmacs
are installed, the main menu shows also the XEmacs entries under the
"Emacs" heading. (Whereas the original dir section is called
"XEmacs Editor".)

Is this behaviour intentional? It would be trivial to change
Info-streamline-headings so that "Emacs" is only matched at the
beginning of a word.
