Re: read-file-name error-handling problem

[Richard Stallman]

I figured out the cause of this.  Qerror in the handlerlist->handlers
is used as a special signal meaning "handle all signals and let the
debugger run".  This was supposed to apply only to
internal_condition_case, but in fact it applied to condition-case
also.

It is not hard to fix this; the only worry is whether any Lisp code
depends on this.  (Though the Lisp manual does not describe this
behavior.)
