In addition to passing the file path through `expand-file-name',
tramp-style remote file names are converted to conventional (local)
file paths. The reason is that, if a tramp file name was in use in
emacs, then the shell command will be executing on the remote machine
in question. Further, by default the file name is passed through
`shell-quote-argument'.
