I have tested it and it works fine in general. I only found a strange
behaviour in one case. I have a script which defines a cmap to <CR> and
calls a function via <C-\>e. When the function name is XX() everything
works fine, when the function name is WrapCmdLine() after pressing enter
in the expression register command line is not redraw, though it has
changes, since when I press <space><bs> it gets redrawn with the value
of the expression in the right place. You can test it with the attached
script. The function XX()=WrapCmdLine() only modifies the behaviour of
the cmdline when the cmdline starts with "! " sending the command line
to system() function rather than to the terminal directly.
I was testing with:
./vim -u NONE -i NONE --noplugin
