Hmm. In `tramp-find-file-exists-command', it is correctly tested for
"test -e", "/bin/test -e" aso. But the cache seems to get the wrong value.

I would need to analyze the cache operations. Would you, please, apply
"M-x tramp-cleanup-all-connections" (this also removes cache settings),
set `tramp-verbose' to 9, and rerun the test? The resulting debug buffer
shall tell us more.

Maybe the Tramp info file shall be improved for recipes how to disable
the cache for debugging.

Best regards, Michael.
