web: the config cast turns the layout before it edits

C-a e arrived as a strip along the bottom, and a 66-line config in a
twelve-row strip reads like a keyhole. A quarter turn (C-a Space)
right after it opens makes the editor a column with the height the
file deserves -- and shows off the rotate while at it.

The column brought back vim's hit-enter stall (the file-info message
wraps at 49 columns), so the recording's EDITOR gains the same
shortmess the webdemo's vimrc already carries.
