Encrypting messages truncates trailing whitespace

try this on a *nix command line.....
$ echo 'test ' | gpg -ear <your-key-ID> | gpg | tr ' ' 'x'
it'll prompt you for your password to decrypt the encrypted message, and
then after decrypting, it will convert spaces into "x"s.
i'm using gpg 1.2.4 and encryption/decryption on my system *does* preserve
trailing spaces. if you get the same results, then gpg isn't the culprit.
i'm not sure, but i think one of the SMTP RFCs specifies that trailing
spaces can (should? must?) be disposed of, so your MUA might be doing
the parts of the OpenPGP RFC (2440) that mention trailing spaces don't
seem to apply here. on my reading of it, it seems that trailing spaces are
ignored by signature applications, but it doesn't say anything about
disposing of those trailing spaces. indeed, they seem to be preserved even
when signing (at least on my machine).
