bug#5221: 23.1; read_escape too greedy with "\x"

From: Łukasz Stelmach
Subject: bug#5221: 23.1; read_escape too greedy with "\x"
Date: Tue, 15 Dec 2009 13:29:33 +0100
User-agent: Gnus/5.13 (Gnus v5.13) Emacs/23.1 (gnu/linux)

Emacs (read_escape() function at lread.c file) interpretinterprets
"\x3a480" string as "0x3a480" instead of ":" and "480" coming next.
Some software (most? gnupg to name one) assume these escapes represent
single bytes.

Try interpreting "\x3a480" in the *scratch* buffer.

IMHO the while() loop in read_escape for c='x' should depend on
"count < 3" condition.

Why would anyone use multibyte "\x" sequence instead of "\u" one anyway?
