Ron Yorston 7a8ceb4eb2 vi: changes to line addresses for colon commands

Make line addresses behave more like vi:

- Vi allows the user to enter an arbitrary number of addresses,
  though only the last two are used.  This simplifies get_address()
  by reducing the amount of state that needs to be carried.

- When a command requires a single address the last one entered is
  used.

- If addresses are separated by a ';' instead of a ',' the current
  line is updated to the left address.  This may be useful when a
  search is used to specify a range, e.g. ':/first/;/last/d'.

- When the last address is empty it should refer to the current line.
