This is from the man page of PGP2.6.3in: CLEARSIG - Enable Clear-Signed Output Default setting: CLEARSIG = on Normally, a signed and ASCII-armored PGP message is gib­ berish, even though the text is not encrypted. This pre­ vents munging by mailers, but requires PGP to simply read the message. If CLEARSIG is enabled, then when signing and ASCII-armor­ ing 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. So it seems it's not possible to turn off the escaping of "From " lines in PGP without turning of clear-signed output. But this would lead to messages which are unreadable by people who don't use PGP because then the signed message will be Radix64 encoded.
