[oe] multiple entries in PREMIRRORS

[Cliff Brake]

I've been trying to set up multiple entries in PREMIRRORS in a conf file like:

PREMIRRORS = "(ftp|https?)$://.*/.*/ http://dev.bec-systems.com/oesources/ \
http://downloads.sleepycat.com/db-4.3.29.tar.gz
http://dev.bec-systems.com/oesources/db-4.3.29.tar.gz"

which results in:

NOTE: Resolving missing task queue dependencies
NOTE: preferred version 2.5 of glibc not available (for item
virtual/arm-angstrom-linux-gnueabi-libc-for-gcc)
NOTE: Preparing runqueue
NOTE: Executing runqueue

rerun and 1 failed.
ERROR: '/build/pp/oe2-test-package-fetch/oe/custom/packages/linux/compulab-pxa270_2.6.25-rc5.bb'
failed

But, if I define a new class:

bec-mirrors.bbclass:

PREMIRRORS_append () {
ftp://.*/.*/	http://dev.bec-systems.com/oesources/
http://.*/.*/	http://dev.bec-systems.com/oesources/
http://downloads.sleepycat.com/db-4.3.29.tar.gz
http://dev.bec-systems.com/oesources/db-4.3.29.tar.gz
}

and put the following in *.conf:
INHERIT += "bec-mirrors"

it works fine.

What is the difference?  Why do multiple lines work fine in a
PREMIRRORS_append, but not directly assigning a variable?  I started
tracing through the code, but its bouncing back and forth between
bbclass and bitbake code, so I'm asking first :-)

Thanks,
Cliff
