In this case, a change was made in one-true-awk from *FS to
getsval(fsloc) in a line just after one of the lines that had the 0 ->
NULL change. It works both ways as far as I can tell. It looks like a
bug fix, but I've not tried to track down which ancient version of
one-true-awk it was in (github starts too late for tracking this
down). Before and after the changes the regression suite is passes
100% relative to the un-modified one-true-awk.
The conversion of 0 -> NULL required a rebase at some point, as noted
in r301289 when pfg commited it. In that rebase, three lines remained
that had been removed in a prior version of awk, and one of them had a
0 -> NULL change causing a conflict. The conflict should have been
resolved by removing the three lines, but wasn't. This introduces a
regression into f.split3 test which prior to this commit we were
failing, but a pure onetrueawk wasn't. Remove the offending 3 lines.
Note: this backs out a number of changes we've made to awk because
they aren't upstream, but are on the vendor branch. Those will be
reapplied. svn makes it needlessly difficult to know which ones, but
at least r315426, r301289, and maybe r301691, though there may be
others too. None of these are critical, so bisecting through this
point is safe for all but awk regression tests :).
gawk allows multiple arguemnts to bit-wiste and, or and xor
functions. Implement an arbitrary number of arguments for these
functions. Also, use NULL in preference to 0 to match rest of file.

using tabs instead of spaces after #defines added.

While none of them is considered even near to cryptographic
level, random(3) is a better random generator than rand(3).
Use random(3) for awk as is done in other systems.
Thanks to Chenguang Li for discussing this in the lists
and submitting the patch upstream.

- Make one-true-awk respect locale's collating order in [a-z]
bracket expressions, until a more complete fix (like handing
BREs) is ready.
- Don't require a space between -[fv] and its argument.
