In OurDelta builds from patchset d7.
(only the mysqld_safe fix in the end, the my_print_defaults doesn't appear to
be used elsewhere relevant so this is sufficient)

Status in OurDelta - Builds for MySQL: Fix Released
Bug description:
mysqld accepts both dashes and underscores in server options, however
mysqld_safe does not.
Since it's unclear from the user's perspective (and they shouldn't NEED to
know!) which options get processed only by mysqld_safe, this can mean that they
use an option in the wrong way but don't notice it.
Example... open_files_limit
When written like that, it mysqld_safe will not recognise it and thus not call
ulimit -n
...
The option WILL be feed to mysqld so it shows the "correct" number in SHOW
GLOBAL VARIABLES. Except, since ulimit wasn't called, it's not actually in
effect!
