Re: M-x man could better guess neighboring word

My cursor is at "_":
address@hidden:~$ crontab _
and I do M-x man, and it doesn't prompt me with the default of
crontab, instead I have to move the cursor back a bit and try again.
emacs-version "22.1.1"

Please try the attached patch.  Would you find it useful to
search previous lines, the remainder of the current line,
following lines?  Should we skip any non-whitespace chars?
