  1. [9fans] xd bug

    Hello. Regarding my previous question, the file /n/sources/contrib/
    pietro/xd.out shows a bug in xd regarding characters that can't be
    printed with the %c format. There should be no space between a non-
    printing and a printing character; but the two spaces screw the rest
    of the line up. This shows a deficiency in the table-based
    implementation. I'll do my best to fix it in a clean way. Thanks.

    It would help a lot if (1) you cut and pasted things into email
    instead of making us go look on sources for four-line files
    and (2) you told us exactly what you thought was wrong.

    Your xd.out says:

    % xd -c -x bad
    0000000 e0 Q R S \n
    0 e0515253 0a000000
    0000005

    which looks fine to me. If I create the same file and add some
    more text just to fill things out, I get:

    % xd -c -b -x a | sed 6q
    0000000 e0 Q R S \n L o r e m i p s u m
    0 e0 51 52 53 0a 4c 6f 72 65 6d 20 69 70 73 75 6d
    0 e0515253 0a4c6f72 656d2069 7073756d
    0000010 d o l o r s i t a m e t ,
    10 20 64 6f 6c 6f 72 20 73 69 74 20 61 6d 65 74 2c
    10 20646f6c 6f722073 69742061 6d65742c

    which still looks just fine. In particular I don't see any
    alignment difference between the first line and the second line.
