For unknown reasons it does not have the trailing space in `:args`
output there anymore:
[ FAILED ] test/functional\ex_cmds\arg_spec.lua @ 11: :argument does not restart :terminal buffer
test/functional\ex_cmds\arg_spec.lua:25: Expected objects to be the same.

stack traceback:
test/functional\ex_cmds\arg_spec.lua:25: in function <test/functional\ex_cmds\arg_spec.lua:11>
The test is not about that though, and this can be made less strict by
using `trim()`. The new test in `test_arglist.vim` for no trailing
newline is OK, and contains trailing spaces. So this is likely due to
the length of it exceeding the column width already.
