so it can be run on any platform.

There was an improper order of doing chained operations.
  
To the documentor: ENABLE|DISABLE KEYS combined with RENAME TO, and no other
ALTER TABLE clause, leads to server crash independent of the presence of
indices and data in the table.

Problem:  When we have a really large number (between 2^63 and 2^64)
as the left side of the mod operator, it gets improperly corerced
into a signed value.

Solution:  Added check to see if the "negative" number is really
positive, and if so, cast it.

	with embedded spaces
  
Problem:  Original code written assuming password contains no spaces.
Further, because of how sh interprets characters in variables, you
cannot do the "simple solution".
  
Solution:  Move the "was a password provided" check to the end. This
allows us to correctly quote the password argument when passed to the
mysql client program.  Addendum:  Put this check inside of a shell fn
to simplify the code.

The problem was that THD::row_count_func was zeroed too. It was zeroed
as a fix for bug 4905 "Stored procedure doesn't clear for "Rows affected"
However, the proper solution is not to zero, because THD::row_count_func has
been set to -1 already in mysql_execute_command(), a later fix, which obsoletes
the incorrect fix of #4095
