vi: handle autoindent in 'cc' command

When the 'cc' command is invoked with autoindent enabled it
should use the indent of the first line being changed.

The size of the indent has to be established before char_insert()
is called as the lines being changed are deleted.  Introduce a
new global variable, newindent, to handle this.  The indentcol
global is now effectively a static variable in char_insert().
