igrep only supports ange-ftp (and efs) to the extent that the
igrep-visited-files and Buffer-menu-igrep commands explicitly ignore
remote files.

To properly support remote files, igrep would need to invoke the grep
command in a remote shell.  I know there has been discussion about
whether Emacs should implement process handlers, so that tramp could run
programs on a remote host when invoked from a buffer visiting a remote
file.  But I don't know what was decided and implemented (if anything).
