Though I have not yet read entire discussion, you are talking about
non-MIME encryption?  If so, it might be preferable that --textmode is
specified only in that case.

If --textmode is specified, gpg _itself_ converts line ending.

On the GNU/Linux system:

$ ruby -e 'puts("abc\r\ndef\r\nghi\r\n")' > test.txt
$ gpg -q --encrypt --textmode -r ueno@unixuser.org test.txt
$ gpg -q --decrypt test.txt.gpg > test.txt
You need a passphrase to unlock the secret key for
user: "Daiki Ueno <ueno@unixuser.org>"
...
$ hd test.txt
00000000  61 62 63 0a 64 65 66 0a  67 68 69 0a              |abc.def.ghi.|
0000000c

All CRLF are converted to LF.  This might cause a problem if you send an
encrypted and signed data in RFC1847 encapsulation (RFC3156, section
6.1).  After decryption, it does no longer contain the signed material
identical as before encryption.

Please add *me* to the Cc: list if you mention changes obviously
conflicting with my intension such as below.  Otherwise, I will not be
aware of them.
