Pardon me if I'm confused here, but wouldn't that involve checking any
failing detached text-mode signature a second time with the original data
without trailing whitespace stripped to see if it then passes?
And isn't it impossible to both follow the RFC and generate detached
text-mode signatures that will verify correctly with PGP 5.0 if the data
has trailing whitespace? In that either the signatures will verify with
PGP 5.0 or they will verify with RFC-compliant checkers, but never with
