This patch introduces the following changes:

The crash-on-exit bug in Version 12.16/12.17 has been eliminated. 

The fix-in-place routines have been enhanced. The result of this is
that directories with problems are much more likely to be fixed,
rather than eliminated. DiskSalv's ability to deal with various kinds
of bad blocks linked into the active disk partition is also much
improved.

New startup and stack extension code solves stack overrun problems
completely. This may have some small effect on performance, but it
should eliminate at least half of the problems folks have been having
with DiskSalv.

A new command option, SKIPDEVS, has been added. This is used to keep
DiskSalv from examining specific DOS devices.
