vi: improvements to character search within line

- Use a common routine to handle all commands to search for a
  character in a line.

- When searching for the nth occurrence of a character don't move
  the cursor if fewer than n occurrences are present.

- Add support for the 'T' command, search backwards for character
  after next occurrence of given character.
