Re: New easymenu behavior

recentf simply uses (easy-menu-add-item nil '("files") ...) to add the
recentf menu into the "File" menu which is identified with the 'files
key symbol. This worked well in 21.3 because the code just interned
"files" to get the key symbol.

In 21.4, before the last change to easy-menu-intern, that worked too
because the code interned the downcased strings in the menu path.

Now it fails because "files" returns the symbol 'Files as the key to
locate the menu item.

IMHO, the 21.3 version looks better because it doesn't change the
meaning of strings given to locate a menu item.  So it should be able
to locate "Greek" as a different menu item from "greek".

Notice that XEmacs directly use menu item names to locate them.  For
example you can use '("File") to locate the "File" menu in the menu
bar. Maybe is it a better mechanism to use in external libraries?
