[tor-dev] Tor Directory Meta-Format + Line Wrapping?

Hi,

Looking at the specification for the Tor directory protocol's meta-format, it has some text on line wrapping:

When line wrapping, implementations MUST wrap lines at 64 characters. Upon decoding, implementations MUST ignore and discard all linefeed characters.

I can't work out how an implementation is meant to know if a linefeed character is meant to be for line-wrapping or if it's meant to be the end of a keyword line.

Are there any implementations that actually do line wrapping?

Thanks, Iain.
