PGP has this issue with 'clear-signed' output. An excerpt from the pgp
man page:
If CLEARSIG is enabled, then when signing and ASCII-armoring a text
file, PGP uses a different format that includes the plaintext in
human-readable form. Lines beginning with "-" are quoted with "- ".
To cope with some of the stupider mailers in the world, lines
beginning with "From" are also quoted, and trailing whitespace on
lines is stripped. PGP will remove the quoting if you use it to
decrypt the message, but the trailing whitespace is not recovered.
This is still useful enough to be enabled by default.
You might find more details about typical mailer-munging from the PGP docs
or source.
