What I had in rancid 2.8:

# This routine parses "show flash"
sub ShowFlash {
    # skip if this is 7000, 7200, 7500, or 12000; else we end up with
    # redundant data from dir /all slot0:
    print STDERR "    In ShowFlash: $_" if ($debug);
    $redacted = 0;      # -LR- set if a file listing is suppressed

    while (<INPUT>) {
        tr/\015//d;
        last if (/^$prompt/);
        next if (/^(\s*|\s*$cmd\s*)$/);
        ### -LR- ideal would be to ignore filesystem changes like date
& time, but I'm not there yet
        ### -LR- so ignore the whole thing
        if (/startup-config\s*$/)       {$redacted = 1; next; } # -LR-
        if (/private-config\.text\s*$/) {$redacted = 1; next; } # -LR-
        if (/config\.text\s*$/)         {$redacted = 1; next; } # -LR-
        if (/dhcp[-_]database\s*$/)     {$redacted = 1; next; } # -LR-
ignore dhcp database changes
        if (/dhcp-snooping(-data)?\s*$/){$redacted = 1; next; } # -LR-
ignore dhcp snooping database changes
        if (/lic_uom\.dat\s*$/)         {$redacted = 1; next; } # -LR-
ignore .private/lic_uom.dat changes
        if (/.*\(\d+ bytes (free|used)\)/) {            # -LR- want to
show bytes used?
           if ($redacted) { next; }                     # -LR-   not
when there are files that haven't been shown
        }                                               # -LR-
