vi: fix replacement of single character with CR

Browse Source 
Currently if the 'r' command is followed by a carriage return a
literal CR replaces the current character.

Fix this so that:

- a new line is inserted
- the autoindent setting is respected
- the cursor is placed at the start of the new line
