I agree that this does not prove anything. But gawk is late to the party
with support for inplace editing, and I think it can be useful to look
at how other tools implement this feature. One presumes that they all
use a similar mechanism. We are not changing the file, just replacing it.
So we care only about the directory's permissions.

Sorry. I see from comp.lang.awk that what you really want is to disable
the inplace feature for a single file. Using "chmod -w" is not a great
solution to that problem, I think.
