Instead we see the following call chain:
describe-function => require(shortdoc) =>
file-remote-p("/ssh:user@host:/tmp/foo") =>
error: (void-function "get-process")
The call of file-remote-p in shortdoc is triggered by Tramp's
integration there. It should be harmless (always returning if Tramp is
enabled).
However, we see the error (void-function "get-process"). Likely, this is
just for DOS builds of Emacs.
Does the following patch fixes this?

If it is set to nil, all remote file names are used literally. Don't
set it manually, use `inhibit-remote-files' or `without-remote-files'
Best regards, Michael.
