[tex-live] fixes to man pages: pdfetex, pdftex, tcdialog, tex, texdoc, texdoctk, updmap, xdvi, updmap.cfg

[Karl Berry]

    What is the source of tcdialog man page?

source/utils/dialog/dialog.man

I kind of doubt Marc Ewing is maintaining it any more either, but please
write him (see the README).

    Leaves xdvi man page. I guess I have to send it to Ulrik afair.

Yes please.  Or tex-k at tug.org or
http://sourceforge.net/tracker/?group_id=23164&atid=377580.

Thanks,
karl
