There are many (hundreds and hundreds) of non-trivial diffs between
the released version of pdksh and the OpenBSd version.
Sometimes with Open you forget that you have an audited OS that has
been beaten into submission and uniformity. This process has
obviously been applied to ksh, and I'm pleased to see it. Many of
the diffs are "trivial" (eliminating dead code in ifdef's for other,
inferior operating systems), some are simply applying BSD formatting
conventions to the source, many are good "lint-picking" changes,
others appear to be the result of feature enhancement, reliability
and security considerations. Some, like the numbering of lists,
appear to be simply feature choices that OpenBSD made (they
reprogrammed a LOT in that area) for reasons of style or personal
taste, but probably to conform to some other version of ksh, possibly
the original Korn/AT&T version. Maybe we should ask on misc@ about
that.
That's the nice thing about OpenBSD -- when you look inside you see
good things, not a writhing nest of vipers. I wish they'd rewrite X.
