If diff(1) is called with -y or -D, it produces output even if the files are identical. RCS recognizes this behavior and doesn't optimize out the case where it knows that the files/revisions will be identical if -y or -D are used (this is the purpose of `no_diff_means_no_output'). Your patch removes this 'intelligence' and as a result, rcsdiff will always skip diff generation when the revisions are identical, which is wrong if the user specified -y or -D. The "bug" is that RCS considers a long option name as a case where we don't know if diff(1) will produce output or not; indeed if the long options are --side-by-side or --ifdef (the long counterparts of -y and -D) then there will be output even if the revisions are identical. -- ,''`. : :' : Romain Francoise <[EMAIL PROTECTED]> `. `' http://people.debian.org/~rfrancoise/ `- -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
