Mostly manpage-shuffling according to the changes in the corrigendum,
wording changes and more idiomatic expressions.
All this is finished up by marking the POSIX 2013 conformant tools
with
.St -p1003.1-2013
which is not available in older mandoc builds or nroff, but which
reflects what we actually did, so who cares?
This is a huge step and it's not far until we can release sbase 0.1.
1) Update manpage, refactor the HLP-section and other wordings.
2) BUGFIX: If chmod() fails, don't recurse.
3) Rewrite the arg-loop, fixing several issues:
BUGFIX: Handle multi-flags (e.g. -RH)
BUGFIX: Properly handle the termination flag --, error on e.g. --x
BUGFIX: Error out on an empty flag -.
4) Refactor logic after the arg-loop, which is now simpler thanks
to argv-incremention.
- add .Os, it is mandatory.
- don't redeclare .Nm when it's not needed.
- fix some warnings (checked with mandoc -Tlint).
- remove some leftover old stuff.
and mark it as finished in README.
One small rationale on the way the manpage is set up: Looking at
the coreutils manpage, it does not invite to be a quick reference
guide, whereas I wrote this manpage to be short and concise in regard
to the information the advanced user needs.
No one needs to explain what an octal number is. That's not part of
the scope of this manpage.
Also, nobody wants to read a block of text just to find out how
to build an octal mode string.
