Maybe you can bring them in here? :)

Import the awk(1) manpage from OpenBSD
As discussed during AsiaBSDcon devsummit, import the manpage from OpenBSD which
is has been rewritten in mdoc(7) format making it readable by default with
mandoc, it also has been extended by OpenBSD to cover all awk(1) options
Obtained from: OpenBSD
MFH: 1 week
One problem noted today by imp@ is that this doesn't quite document the awk we
ship:
% echo 42 | awk '{ print lshift($1, 1) }'
awk: calling undefined function lshift
input record number 1, file
source line number 1
None of the bit operations described in this manpage are implemented in
one-true-awk. Hmm, it seems that OpenBSD added those as a local patch
relative to one-true-awk in 1.10 of lex.c. So Someone(tm) needs to probably
compare OpenBSD's awk to one-true-awk to see what local changes they have
and either update the manpage here or pull the local diffs across. (I'd
probably we just grab the implementation for the bitwise ops myself.)
Hmm ...
TBH, many years ago I tried to upstream the OpenBSD (actually gawk)
extensions but upstream (bwk) was not interested.

One problem noted today by imp@ is that this doesn't quite document the awk we
ship:
% echo 42 | awk '{ print lshift($1, 1) }'
awk: calling undefined function lshift
input record number 1, file
source line number 1
None of the bit operations described in this manpage are implemented in
one-true-awk. Hmm, it seems that OpenBSD added those as a local patch
relative to one-true-awk in 1.10 of lex.c. So Someone(tm) needs to probably
compare OpenBSD's awk to one-true-awk to see what local changes they have
and either update the manpage here or pull the local diffs across. (I'd
probably we just grab the implementation for the bitwise ops myself.)
