in reply to grep and find file weirdness

Yes, the is_dos_format() is smashing $_ in your grep block. The easy fix is to either local()ize $_ in the function or use a different variable in your while loop:
sub is_dos_format { local $_; ... } # or sub is_dos_format { ... while (my $line = <RJA>) { ... }
