I did something slightly different, inspired by your suggestion. I wrote 
up a quickie script to get the magic number returns from 'find' on all 
my dotfiles. This after running several different combinations of 'cat' 
with options. Re ALL the files in question:  there were *NO* ^M markers 
at the end of any line.  I regard running dos2unix a waste of time if I 
don't see some indication of non-Unix encoding/formatting on a file or 
files ahead of time. And I may not know much but I know what to look 
for. Or maybe you'd prefer to take up the subject of what saves which 
correctly with the developers of Emerald Editor, which I use both in 
Windows and Ubu Linux to compose scripts and edit dotfiles regularly 
when I'm not in the mood for the mouseless approach vi and nano restrict 
one to.

A solution that's not a solution isn't even worth considering (was that 
Einstein or Schrodinger? Maybe it was Dr Moore.)

Attached is the output to text of that script (which returned as 
"*magic_returns_dotfiles.txt: ASCII text*" one-half second ago).
