patches to: cron(8), printf(1), man adw(4), man polling(4)

[Matthew Dillon]

:OK, four patches attached (and if any of them are going overboard, just
:feel free to ignore them of course):

    All in!  For rollup patches, please submit just a single patch (e.g.
    from /usr/src a 'cvs diff share/man/man4 usr.bin/printf usr.sbin/cron').
    I can still commit them independantly as appropriate, but it's easier
    for me to patch with just one patch file then multiple independant files.
