bug#5692: rfc822-addresses returns a string on occasion


From: Uday S Reddy
Subject: bug#5692: rfc822-addresses returns a string on occasion
Date: Sun, 07 Mar 2010 15:24:14 +0000

A change made to rfc822.el in Emacs 23.1 seems to have introduced a
bug.  As the following calls illustrate, the function rfc822-addresses
normally returns a list of strings, but in the last case it is
returning a string.  This problem was not present in 22.3.

(rfc822-addresses "address@hidden")
("address@hidden")

(rfc822-addresses "foo:@bar")
("(Unparsable address -- Gubbish in middle of :...; group: 
\"foo:address@hidden")")

(rfc822-addresses "foo:;@bar")
"(Unparsable address -- Strange character \\@ found: \"@_^_bar\")"

------

More generally, it is not clear to me why rfc822-addresses is
returning strings instead of throwing errors when it finds bad address
strings.  From the code in VM, it appears that it was originally
expected to throw errors.  But that has changed sometime in the course
of revisions.

Cheers,
Uday
