trouble with :also-exclude

[Attila Lendvai]

i'm not sure what's the expected behavior. what i'm trying to achieve
is to exclude some dirs inside my ~/common-lisp/

--------

$ cat ~/.config/common-lisp/source-registry.conf.d/00-excluded-systems.conf
(:also-exclude "sbcl" "disabled-systems")

$ rlwrap sbcl --no-userinit --no-sysinit

* (require :asdf)

("ASDF" "asdf" "UIOP" "uiop")
;; force asdf upgrade
* (asdf:load-system :asdf)

T
* (gethash "cl-postgres+local-time" asdf::*source-registry*)

#P"/home/alendvai/common-lisp/disabled-systems/local-time.old-darcs/cl-postgres+local-time.asd"

 "autom4te.cache" "cover_db" "_build" "debian")
* asdf/upgrade:*asdf-version*

"3.1.5.18"

----------

it may or may not be normal that *source-registry-exclusions* doesn't
contain "disabled-systems".

(trace asdf/source-registry::process-source-registry-directive :print
asdf::*source-registry-exclusions*)

the output of the above^ trace suggests that it gets processed (and
recorded into a dynamically bound variable? which is then thrown
away?).

any hints?
