You mean, for all man programs?  I considered this as well, but I just
don't feel like making things worse for the two man programs which are
used on GNU-based system, and which do have a single page name per line,
and at its beginning (quite reasonably so, and in the spirit of POSIX
man(1p), I'd say).  So perhaps the second patch I proposed (without the
test for valid output of `man -k ^')

would be better, after all, even though the
Man-keyword-completion-anchor variable is ugly.
