From a drawin host, visit a file on a non-darwin remote host via tramp,
using C-x C-f /sshx:HOST:/DIR/FILE

From that buffer, try to visit another file on that same host, or simply
trigger file name completion by typing e.g. C-x C-f TAB

Instead of the desired result, you will see an error message such as

  tramp-file-name-handler: Lisp nesting exceeds ‘max-lisp-eval-depth’

(See below for analysis and a proposed patch.)

Using debug-on-quit, I obtained the following backtrace:

The problem here is that tramp ((TRAMP-COMPAT-TEMPORARY-FILE-DIRECTORY))
evaluates the standard value of TEMPORARY-FILE-DIRECTORY (defined in
cus-start.el), which calls SHELL-COMMAND-TO-STRING on the remote system,
and also FILE-DIRECTORY-P, which will be replaced by tramp's version on
the remote system.  My remote systems are GNU/Linux, not Darwin, and the
"getconf DARWIN_USER_TEMP_DIR" command returns

"getconf: Unrecognized variable `DARWIN_USER_TEMP_DIR'"

According to a comment in cus-start.el, the FILE-DIRECTORY-P should
handle that case:

				 ;; Handles "getconf: Unrecognized variable..."
				 (file-directory-p tmp)

...but in the remote case, FILE-DIRECTORY-P will end up recursively
calling TRAMP-COMPAT-TEMPORARY-FILE-DIRECTORY.

TRAMP-COMPAT-TEMPORARY-FILE-DIRECTORY can be fixed by disabling
TRAMP-MODE around its evaluation of the TEMPORARY-FILE-DIRECTORY
expression:

This change is consistent with the comment in the function that says
that a local directory should always be returned.

I don't know whether the top-level (DEFVAR TRAMP-MODE) is the correct
idiom for making sure we bind the global variable TRAMP-MODE, which is
defined in another file using DEFCUSTOM.  Please advise.
