I came up with the following. It basically is a pair of typing-saving
canned s/// command which replaces all consecutive horizontal whitespace
with a given number of linebreaks throughout the buffer, in a range or in
the current visual selection, in the second version restricted to
horizontal whitespace after sentence-final punctuation.
" Command :Wl [{N}] (*W*ord *l*ine)
" Replace consecutive horizontal whitespace in buffer/range/selection
" with N line breaks (Default: the number in variable g:Wl_line_breaks)
let g:Wl_line_breaks=1
:com! -range=% -nargs=? Wl exe
printf('<line1>,<line2>s/\s\+/%s/g',repeat('\r', (<q-args> ? <q-args> :
g:Wl_line_breaks)))
" Explanation:
" -range=%
" The command operates over the whole buffer or over a given range,
which
" may be visual.
" -nargs=?
" The command takes an optional argument.
" exe printf(...)
" Constructs a string containing the actual command, then executes this
" string as a command.
" (<q-args> ? <q-args> : g:Wl_line_breaks)
" Compute N: use the argument if there was one (and it was non-zero)
" or else use the number which is the value of the global variable
" g:Wl_line_breaks, which must be defined.
" It is up to you to make sure that the argument and the variable value
" are positive integers!
" repeat('\r', N)
" Construct a string which will be interpolated as N linebreaks.
" The string doesn't actually contain linebreaks, but they will "become"
" line breaks when the command is executed.
" s/\s\+/%s/g
" Here %s will be replaced with N linebreaks,
" so if N is 1 it's s/\s+/\r/g
" and if N is 4 it's s/\s+/\r\r\r\r/g
" so basically replace all consecutive horizontal whitespace
" with the desired number of linebreaks.
" Command :Sl [{N}] (*S*entence *l*ine)
" Replace consecutive horizontal whitespace *after a ./?/!*
" in buffer/range/selection with N line breaks (Default: the number in
variable g:Sl_line_breaks)
let g:Sl_line_breaks=1
:com! -range=% -nargs=? Sl exe
printf('<line1>,<line2>s/[.?!]\zs\s\+/%s/g',repeat('\r', (<q-args> ?
<q-args> : g:Sl_line_breaks)))
" Explanation:
" This is basically the same as above, but requires that the horizontal
" whitespace is preceded with a "." or "?" or "!", and it has its own
" variable for the default value of N.
" Mappings to execute :Wl/:Sl (without argument) over buffer/selection
nor Wl :Wl<cr>
nor Sl :Sl<cr>
And, how to use it on highlighted text in visual mode, instead of

The commands above and the command from yesterday work on an existing or
previous visual selection too. If you have a visual selection and press :
the commandline is prefixed with '<,'> which is a range equal to the lines
holding the visual selection. You can also insert that range manually to
restrict a previously used command to the latest visual selection.
The mappings above work either on the whole buffer or the visual selection,
so just make a visual selection and type Wl and it just happens in the
visual selection.
In yesterday's installment the
vnor Jp :Jp<cr>
means that you can make a visual selection and just type Jp and have the
:Jp command applied to the selection. Just make sure that the selection
ends with a blank line. The
nnor Jp ...
line from yesterday does the same over the whole buffer in normal mode,
with the difference that it first inserts a blank line at the bottom of the
buffer to make sure there is one.

It's nothing. I have been using yesterday's command/mappings for ages, and
I will certainly use those from today too.
