(I found a script which tries to figure out the byteorder of a box
by "od -An | grep", but it is POSIX anyway.)
There is a little behavioural change: The whitespace without any arguments
is like "-to2" now; before it was custom. It's not worse imho.
1. Don't add changelog and other implementation specific nvi files because
this have changed from 1.79 and are probably not relevant in 1.81
2. Put back virecover.
3. Descend regularly to subdirs instead of Makefile hacks
4. Use USD.doc stuff from the 1.81 docs except for vi.ref which has
unfortunately been converted to texinfo. For that, we preserve
the original documents because we want to still be able to make
section 13 (building texinfo is not acceptable because it will not
have the same look and feel as the rest of the book)
5. Since the texinfo reference is probably better maintained, build
that too as a texinfo document.
* define NOfoo before .including <bsd.own.mk> or anything else that
might (indirectly) .include it, not after.
* defining MKfoo=no isn't what Makefiles are supposed to do
(yes, both mistakes were present :)
in "vmstat -s" output when run on the active kernel.
The reason we can't easily provide these values out of a crash
dump, is that these fields are no longer proper members of
struct uvmexp, but rather are estimated by and dependent on
the currently active page replacement policy in the kernel.
temprorary directory. Previously, fputs was used without checking the
return value, leading to silent truncation when the temporary
filesystem was full (such as can easily happen when migrating to
tmpfs).
1. long a; int i; a = i * i;
suggests casting i to long, so that we gain precision in the multiplication.
2. warns about magnitude comparisons in enums.
3. warns about possible sign extension issues when integer types become widened.
rare and skipping over normal characters with strcspn is therefore
faster. Further simplify logic by always setting newline and precompute
the size of the string.
OK christos@
Simplify the change (adding -d<depth>) that broke it by noting that
-d0 is supposed to be the same as -s.
Calling fts_set(fts,p,FTS_SKIP) here is also pointless.
