man#init_pager() guesses the ref by the heading, which is usually
uppercase, so we don't know the correct casing. But lowercase is more
common, so use that for the buffer name instead of uppercase.
ref #9156
Before this commit, man#init_pager() always tries to scrape the manpage
name and set the buffer name. That's much less important than avoiding
duplicate buffers and E95. And it doesn't seem to be necessary, usually.
Steps to reproduce:
$ export MANPAGER="nvim -c 'set ft=man' -"
$ man sleep
:Man sleep
Error detected while processing function man#init_pager:
line 15:
E95: Buffer with this name already exists
:ls!
1 h- "man://SLEEP(1)" line 4
2 %a- "man://sleep(1)" line 1
When nroff justifies a line, it fills the line with whitespace to meet
$MANWIDTH. With $MANWIDTH=9999, that of course results in nonsense (and
behaves poorly with 'cursorline' option).
To work around that, instead of trying to hard-justify the lines, just
replace the mega-whitespace with a fixed size of 10 spaces.
Perhaps N/Vim needs a "soft justify" feature?
OpenBSD's man returns all candidates when searching with -w instead of
the first one it finds. So this patch takes the first one if multiple
entries are found.

The argument expansion for :Man depends on the number of arguments given to it
starting at the command itself. But user completion functions always provide the
entire command-line which can include modifier commands like :tab, :vert, etc.
leading to a wrong number of arguments.
Prune all arguments up to :Man.
Fixes#7872.
The comment is incorrect, s:error does need to be called. I thought the
call was unnecessary because it didn't show any message for me but I had
shortmess+=F which was hiding the message.
- Improves compatibility with shell=tcsh.
- man.vim: split read_page into get_page, put_page. Do not split the
window until we know there is going to be output.
- fix synopsis highlighting in other locales. Cannot always rely on the first
line for the section in some locales; instead, use the file path and
explicitly set b:man_sect to the actual section.
- eliminate separate s:man_args function
- simplify logic: do not reuse buffer content
- introduce b:man_default_sects Fixes#5233
- introduce <Plug>(man_vsplit), <Plug>(man_tab)
- simplify regexps
This is necessary incase the buffer was previously opened in a different
tab, in which the window options there do not carry over. It is not
explicitly documented in ':help local-options' but that is how it works.
Regression from #5168. Also changed the Man command's nargs to '+' so
that man#open_page does not need to handle 0 arguments, because that
will never occur.
