Honestly, I could probably live with that; the killer is the impossibility
of recovering from white space damage.  I have had many things happen to
code over the years which required someone to run them through indent/cb.

Yes.  It does not create an impression that this is an engineering tradeoff
which has been considered and understood; it creates the impression that
people are defensive enough about it that they're not able to confidently
acknowledge the shortcomings while maintaining that the tradeoff is worth
it.

I like C.  If you tell me that C's macro processor sucks, I will agree
with you.  I don't have to make excuses or pretend that there's no
downsides; I can justify my preference for the language even *granting*
those downsides (and downsides aplenty are to be found).

Amen.

I am fine with this tradeoff.  It's not what I would have picked, but
hey, I'm not Dutch.  What I'm not fine with is people telling me that
it's not a tradeoff and that all the problems are my fault.

If someone designed a protocol where a particular kind of file was required
to be sent via email, as plain text, with many lines starting "From ", and
the protocol died horribly whenever it encountered ">From " at the
beginning of a line, no amount of pointing out that the mail servers in
question were wrong would make it a good design for a protocol.

Whitespace damage is, indeed, wrong.  It's a bad thing.  It is an
*extremely common* bad thing, and I fundamentally don't think it was
a good choice to build a system with no redundancy against it.  That
"redundant" information saves our hides on a regular basis in an
imperfect world.
