Summary: ASDF should use define-condition :report

Initial Comment:
Hi,

I wondered why ASDF-1.86.1 badly reports errors in=20
CLISP:

"(asdf:oos "asdf:load-op "clsql-odbc")
; loading system definition from=20
S:\Code\Lisp\clsql-3.0.3\clsql-odbc.asd into #<PACKAGE=20
ASDF14729>
;; Loading file S:\Code\Lisp\clsql-3.0.3\clsql-odbc.asd=20
...
;; Loaded file S:\Code\Lisp\clsql-3.0.3\clsql-odbc.asd
*** - Condition of type ASDF:MISSING-COMPONENT.
The following restarts are available: [...]"

The specific error message "missing component foo" does=20
not appear in the debugger.

Bruno Haible has now been convinced that ANSI CL contains=20
sufficient wording to mandate that printing of condition objects=20
must go through PRINT-OBJECT. As a consequence, GNU=20
CLISP has been changed to take PRINT-OBJECT methods on=20
condition classes into accound. I no longer claim that it's a bug=20
in ASDF.=20
