#452 new defect

Description

From <https://github.com/armedbear/abcl/issues/63>

In a shell:

touch /tmp/*

(probe-file "/tmp/")
; Evaluation aborted on #<FILE-ERROR {7DF4B809}>.
CL-USER> (probe-file "/tmp/\")
; Evaluation aborted on #<FILE-ERROR {4D5E9779}>.
CL-USER> (probe-file "/tmp/%2A")
nil
CL-USER> (probe-file "file:///tmp/%2A")
; Evaluation aborted on #<FILE-ERROR {7DF4B809}>.

The error is: Bad place for a wild pathname.

I had a quick look to see how this could be repaired, but wasn't sure what the right approach is. This stackoverflow answer suggests using "\" as a quote, which is probably the best solution, and would be compatible with what Clozure CL, SBCL and LispWorks? do. I also think the percent escaped character should be made to work.

The specific screw case I had was that there was an accidentally created file with a "*" in a directory that was being scanned for ASDF's system registry, which crapped out because the directory function returned the "*" pathname, and subsequently did a probe on the file.
