The current guidance for install Python packages is to use
python -m pip install <package_name>
Instead of
pip install <package_name>
This ensures that one is using the version of pip that is tied to the
environment's interpreter (and, thusly, its packages). This has [been
endorsed by a core
maintainer](https://snarky.ca/why-you-should-use-python-m-pip/) as
being the recommended way to invoke pip.
As there currently are a few places where the old invocation was used,
attempt to bring them in line.
Fixes#14234
- If the shada file is set with shada option n, use it.
- If the shadafile is NONE, it does not check for file read/write access.
- If the shada file does not exist, try to create it.
Here I use a negative number to decide whether the count has been
explicitly set. I think it unlikely that negative sections will ever be
created given that negative numbers complicate argument handling:
```
$ man -1 foo
man: invalid option -- '1'
```
and given that there's already precedence for alphanumeric sections like
`3p`, `3x`, `n`, etc.

This does work, though:
```
$ man -S -3 baz
```
With `man baz.-3` and `man 'baz(-3)'`, (GNU) man *might* consider `-3`
internally as a section, but in the end reports as if the whole
argument was the name of a topic:
```
$ man 'baz(-3)'
No manual entry for baz(-3)
```

Closes#13411.
In commit 63f0ca3263, `tagfunc` was introduced to
`runtime/autoload/man.vim`. Nonetheless the tag function instead
of using a short buffer name (e.g. `man://foo(3)`) uses the full
path to the man page (e.g. `man:///usr/share/.../foo.3.gz`). This
behaviour is inconsistent with `:Man!`, thus this commit.
Closes#13334
Problem: ruby#Detect() and node#Detect() don't return a [prog, err] pair
which means callers must special-case them.
Solution: align their return signatures with the perl/pythonx providers.
* support for :perl, :perlfile, :perldo and perleval()
* document that the perl provider doesn't currently work on Windows
* document that the perl legacy interface is now also supported
* added perleval() documentation
* import legacy perl interface tests
* only perl 5.22+ is supported
* healtcheck: use g:perl_host_prog if its set instead
using just 'perl' isn't correct as it may not be the version requested.
ditto for 'cpanm', rather go through 'App::cpanminus' to find the latest
perl version

I removed the SunOS stuff since no one uses SunOS and I've never tested
it on there.
I removed the section_flag init as we can just use -S instead of -s
and -S is used by every implementation as far as I know.
This brings man#init's time from 50-70ms to 15-20ms for me.
