We might use a flag which determines, whether remote file name completion
is appropriate. In shell-mode remote file names shall be suppressed, and in
eshell-mode it should be set depending on the command. "cd" should
support remote file names, "*cd" should suppress them. Other packages
use pcomplete as well, like erc and org. Whether they need to handle
remote file names I don't know.

This flag should be checked in pcomplete-tramp, pcomplete-dirs and
whatever other pcomplete completion tables are concerned. This would fix
also the other (minor) bug I've uncovered in shell-mode in my last message.

There are already such flags, which control this kind of completion,
like pcomplete-file-ignore, pcomplete-dir-ignore, pcomplete-autolist,
you name it. What about a new boolean flag pcomplete-remote-ignore?

WDYT?
