fc-fsio: guard against bogus readdir results from the target If the FFS being operated on contains SE K2x0 extended filenames, readdir will return strings that are bad for printing. We need to guard against this possibility, and also against possible other bogosity that could be sent by other alien firmwares.

/*
 * One of several FreeCalypso extensions to RVTMUX is TCH bit access
 * logical channel, and we would like to handle it specially in rvinterf
 * because it's extremely chatty, sending a frame every 20 ms.  If we
 * were to output every TCH frame in our regular log, that log output
 * becomes useless as everything else is drowned out.  Therefore, we
 * implement a hiding mode by default: we only count how many TCH packets
 * were exchanged in between other messages of interest, and report these
 * counts.
