Instead, we add CRLF conversion to the only remaining place
which needs it, ViewVCS. This save many redundant ops in in
many places.
The only other place where this mattered was in
View::add_text_body, but we already started doing CRLF
conversions when we added diff parsing and link generation for
ViewVCS. Otherwise, all other places we used this was for
header viewing and Email::MIME doesn't preserve CRLF in headers.
