Then you need variant with setline(): it does not care about possible newlines
in g:output,
> rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr value:2940
but you need it with last modification that does not care about `after':
let [d, before; d2]=matchlist(getline('.'),
\'\v^(\s*\S{,'.s:maxlinelength.'})')
let lwidth=strdisplaywidth(before)
call setline('.', before.repeat(' ', 54-lwidth).g:output)
> let g:output=substitute(system(s:cmd),'\n','',"g")
system(s:cmd) produces something like "useful message\n" like `system('echo
"useful message"')' does, am I right? You need just system(s:cmd)[:-2] then.

It will be faster if you won't move the cursor, but use setline({line_number},
{text}) instead. I can't see any mistakes though because I don't see enough
code. Your code is a bit strange (I don't get why you need `output' to be
global
and constructed `cmd' to be script-local), but nothing more can be said at this
point.
