Re #7916: haddockumentation of Distribution.Types.VersionInterval.Legacy

This commit affects only comments and documentation comments.

- clarifies existing haddock for `Distribution.Types.VersionInterval.Legacy`
- emphasizes the mathematical structure: canonical Boolean algebra
- adds docs when they were missing
- add some asymptotic complexity estimates
- add comments in the code that explain its function

Note: this module is declared "legacy", but the documentation effort
here can be salvaged to non-legacy code once #7916 is resolved.

Fix scripts without an .hs or .lhs extension

* Pass such scripts with: -x hs script
* Disable extension check for scripts
* Disable running preprocessors for scripts because they're based on
  extension
* Add test case for script with no extension

Resolves #7910

docs: typo

Related: #7073

Testing cabal init for buildable output

Fix #7714: use nroff -man | less as backend for cabal man

Julian Ospald authored 3 years ago and andreas.abel committed 3 years ago

Also: Fix color formatting when PAGER is 'less'

Windows does not have `nroff` (neither has it `man`) and `cabal man`
fails there usually for lack of these backends.

Directly piping into `man -l -` does not work as BSD-`man` does not
understand option `-l`.  More standardized are the building blocks
`nroff` and `less`.

`cabal man` now should behave as pipeline
```
cabal man --raw | nroff -man /dev/stdin | less
```

Also fixed output of `cabal man --raw` so that it does not produce
warnings.

- `.R` removed.  Was warning:
  ```
  `R' is a string (producing the registered sign), not a macro.
  ```

- No quoted 'new-FOO' should appear at beginning of line.  Was
  warning:
  ```
  warning: macro `new-FOO'' not defined (probably missing space after `ne')
  ```

Added to `cabal-testsuite/PackageTests/Man/cabal.test.hs` a check that
the `stderr` output of `nroff -man /dev/stdin` is empty (no warnings).

Remaining problem:

Unfortunately, after quitting `less` with `q` the following error is
displayed:
```
fd:NNN: commitBuffer: resource vanished (Broken pipe)
```
Not sure how to fix this (my attempts failed).

Remove leftover mentions of artifacts.yml

Re #7712: docs: replace broken relative haddock links by https://hackage...

Links like
`<../release/cabal-latest/doc/API/Cabal/Distribution-Simple.html>` in
`.rst` files are all broken.  We replace them by links to hackage,
e.g.,
`<https://hackage.haskell.org/package/Cabal/docs/Distribution-Simple.html>`.
