I was taken by surprise by the following output from md5sum:

$ ls -Glg special/
total 8
-rw-r--r-- 1 144 Oct 24  2014 'C:\nppdf32Log\debuglog.txt'
-rw-r--r-- 1 144 Oct 24  2014  same-contents
$ echo special/*
special/C:\nppdf32Log\debuglog.txt special/same-contents
$ md5sum special/*
\adfc1d2f1b1d6c7fcaa51e857c1a6f68  special/C:\\nppdf32Log\\debuglog.txt
adfc1d2f1b1d6c7fcaa51e857c1a6f68  special/same-contents

00000080
$ 

I don't understand why it pollutes the first field in its output.
I would have thought it sufficient to mangle the filename if it
feels it has to (echo doesn't bother).

Cheers,
David.
