Re: Filter-like command -- but to insert instead of replacing

Thank you for your reply Bram,
And more generally thank you for your great work & continuous
involvement with Vim.

I was out of idea when I posted yesterday, but there is indeed a simple
workaround at least on some Unix-like systems:

:{range}! tee >(wc -l)

But I agree a more generic/cross-platform solution would be better.

For a really generic solution, the command should support a source range
and a destination range-or-address. At some point while experimenting I
thought there could be an option to the `!r` command.

Here is what I had in mind:

:{range-1}r[read]>[range-2] !{filter}

But, as you suggested, we may envision some new `feed` command instead:

:{range-1}fee[d][range-2] !{filter}

{range-1} is the destination range as specified for the `read` command.
[range-2] is the source range whose content is written on {filter} input
stream. [range-2] is optional and is equal to {range-1} if not specified.


What do you think of that?
