fix(inccommand): ignore trailing commands only for *previewed* command #15638

Since the `State` is global, other scripts are unexpectedly affected during the
'inccommand' preview. This commit introduces a new flag for `do_cmdline`, in
order to ignore trailing '|'-separated commands only for the command invoking
the preview.

fix #8796, update #7494
