Subject: 28.0.50; process-file doesn't correctly handle quoted file names
 for INFILE
Date: Sun, 02 May 2021 23:49:57 +0200

Evaluate something like

(process-file "/:/bin/true" "/:/dev/null")

This gives an error

(file-missing "Opening process input file" "No such file or directory" "/:/dev/null")

Other magic filenames for INFILE (such as "/ssh:localhost:/dev/null")
work as expected.  The docstring for `process-file' says that INFILE is
handled by filename handlers, so I think this should work for quoted
filenames as well.

Same for
(process-file "/:/bin/true" nil '((:file "/:/dev/null") "/dev/null"))

Other forms that I think should work, but fail:

(let ((default-directory "/:/usr/"))
  (process-file "/:/bin/true" nil '(t "/:/dev/null")))

(let ((temporary-file-directory "/:/tmp/"))
  (process-file "/:/bin/true" nil '(t "/dev/null")))

Thanks for the quick confirmation! I will extend
files-tests-file-name-non-special--subprocess with your examples, and
push everything then to master.

Yes, I've seen this as well. Shall be fixed by
f50577ea07fd85a1798cc2d41251ab1418fd802f, hopefully.

Sorry for the inconvenience, and best regards, Michael.
