In awk's POSIX documentation,
both online at:
http://man7.org/linux/man-pages/man1/awk.1p.html
and in the awk(1p) man page:
man-pages-posix-2013-a/man1p/awk.1p
bundled in the archive man-pages-posix-2013-a.tar.xz downloaded from:
https://mirrors.edge.kernel.org/pub/linux/docs/man-pages/man-pages-posix/
some instances of '~' (tilde) have been rendered as ' " " ' (space -
double quotes - space - double quotes - space).
Referring to man-pages-posix-2013-a/man1p/awk.1p, these instances are
fixed in the attached patch.
It has been created with plain "git diff". Since I was not able to
find any SCM repository for the POSIX man pages, the commits it refers
to are obviously not meaningful (I created a local git repository to
test "git diff" and "git apply").
The list of fixes has been determined comparing the above documents
with "The Open Group Base Specifications Issue 7, IEEE Std 1003.1,
2013 Edition" at
http://pubs.opengroup.org/onlinepubs/9699919799.2013edition/utilities/awk.html
Thank you for your great job.
Best regards.
