Part of reverting this change:
stat now outputs the full sub-second resolution for the atime,
mtime, and ctime values since the Epoch, when using the %X, %Y, and
%Z directives of the --format option. This matches the fact that
%x, %y, and %z were already doing so for the human-readable variant.
means considering whether to do the same sort of thing with the
newly-added %W (birth time/crtime). Note that %W currently expands to "-"
on systems with no support (e.g., linux).
I don't particularly like the idea of making stat do this:
$ src/stat -c %W.%:W .
-.-
Rather, I have a slight preference to make it do this:
$ src/stat -c %W.%:W .
0.000000000
In any case, I think %w should still expand to "-".
The alternative is to leave %W separate, with no %:W variant.
I.e., %W would continue to print floating point seconds.
In that case, it would be inconsistent with %X, %Y and %Z.
Other preferences?
