If it's not possible to increase the default chunk size to call
process-filter less often (e.g. now for `M-x man RET bash' it's called
90 times), then some users might want to disable this using a new option
like `Man-sync'. OTOH, since most of man pages are much smaller,
maybe this is not a problem.
But still the users need an indication that the formatting
is not finished. grep/compilation and vc display a string
like "waiting..." or "compiling..." in the mode-line, so
man.el could display in the mode-line "formatting..."
