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.

/*
 * Here we implement the writing of RF tables into ASCII text files
 * in our defined format.  This module will also be linked by the
 * standalone fc-cal2text utility, hence our code here needs to be
 * independent of rvinterf and fc-tmsh specifics.
