* make color output toggling simpler and also more robust
* don't unintentionally assert that tests are run in an environment where colors are turned on.

A common issue for users is that the behaviour of the various repl
commands are not documented anywhere despite some of them having complex
behaviour (e.g. `:set` which accepts a specific set of options). This
implements the ability to call `:?|:h|:help` on repl commands to request
detailed help for a specific repl command, while preserving the
behaviour that calling the help command without any arguments prints the
general help text.
Generic help is defined as the first line of the help text.
Detailed help is defined as the entire help text.
This means that `:help :t`, for example, does not error (there is no
detailed help) but instead just prints the single line of help text.
* [ repl ] Use unlines for detailed help (see #2087)
Ideally, the lines affected should be multiline strings. But for some
arcane reason, newlines in those get swallowed in Nix and Windows
**CI** only Ô.o
This was already documented in issue #2087.

* [ fix ] Fix returned status of the `system` function
* [ re #238 ] Fix program error condition of `git diff` call in `Golden`
According to documentation, not only negative exit code means error
`testInDir dir ...` lists all directories in `dir` which contains
`run` files, and such directories are considered tests.
This is done to make test addition/maintenance cheaper.
Convert some test directories to `testInDir`, but not all of them
because
* some directories are listed in several test groups
* other directories are have some tests disabled
* Add trailing newline on non-empty list in unlines
There are several reasons to do that:
* a line in a text file is something which ends with newline,
and the last line is not special
* `unlines []` should be different from `unlines [""]`
* `unlines (a ++ b) = unlines a ++ unlines b`
* Haskell does it
* Change lines function behaviour
Situation I just ran into that I found confusing:
```
Golden value differs from actual value.
Accept actual value as new golden value? [y/N]
N
Invalid answer.
```
Put the dependency checks in the banner, e.g.:
------------------------------------------------------------------------
Base library
✓ Found Chez at /usr/bin/chezscheme9.5
✓ Found node at /usr/bin/node
------------------------------------------------------------------------
* Banners for test pools
* Summary with the list of failing tests at the end
* Option to write the list of failing tests to a file
* Option to read the list of tests to run from a file
* Using these two latest features to add a new make target to rerun precisely the tests that failed last time
