- Change resetpos function to be global (now called resetstatuspos.  Fixes annoying but small odd problem with cursor placement when inserting a file.  This needs to be done better in 1.3 (originally by David Lawrence Ramsey) Added this issue to TODO

- Remove do_preserve_msg, as using -p still gives Pico-style string behavior, so an annoying message every invocation is probably unneeded (all cheer)
