Yes. I think so, too.
1. I can use capture() easily than :redir.
Example:
let foo = capture(":mes")
redir => foo
mes
redir END
Which is the easy to understand?
2. And, the capture() is used for function arguments.
Example:
echo remote_expr("GVIM1", "capture(':mes')")
I think function is better than command to use it in Vim script.
3. I think the patch works well(because I tested it).
But to fix redir is no patches, it is too far to use it in my plugins.
