decrypt adding ^M characters at the end of each line

[Randy Braun]

Anyone have any ideas as to why I am seeing ^M characters at the end of
each line after decrypting a file?

I am using the following:

/sftw/gnupg/bin/gpg --output /path/path/testfile.txt
--decrypt /path/path/testfile.txt.pgp

This is gnupg 1.4.10 on AIX 5.3.12.2
