Fixes#2302, #3336.
Addresses parts of #3155.
Changes include:
- New `lint-selections` command that only lints the current selections,
and allows a custom lint command.
- New `lint-buffer` command that always lints the whole buffer with
the linter specified in the lintcmd option.
- `lint` alias for `lint-buffer`, for backwards compatibility.
- Errors and warnings are now shown in the Error and Information faces,
not hard-coded red and yellow.
- Error and warning flags now use "!" and "?" symbols respectively,
instead of a unicode block, so they can still be distinguished
in a monochrome colour-scheme or by colour-blind users.
- An error flag on a given line always takes precedence over a warning.
- All messages for the same line are collected into a multi-line message.
- We no longer escape tildes in messages, since that change was added
in commit ae339dc (2016) when we started using `%~~` to quote messages.
We stopped using `%~~` in commit 1a2eecd (2018).
- Anything the linter writes to stderr is logged to the *debug* buffer,
not lost.
- If the linter writes to stderr, an error is shown to the user instead
of the usual error/warning count.
- The `lint_errors` hidden option is replaced by `lint_messages`,
because it contains warnings as well as errors.
- `lint-next-error` renamed to `lint-next-message`,
and `lint-previous-error` renamed to `lint-previous-message`
for the same reason.
- New `lint-next-error` and `lint-previous-error` aliases,
for backwards compatibility.
- `lint-next-message` and `lint-previous-message` show the message
they jump to.
- Where `lint_errors` was a range-specs option, `lint_messages` is a
line-specs option to keep things simpler. This means lint-next-message
and lint-previous-message no longer jump to a specific column.
The first line returned by `aspell` isn't always an identification
string, it can also be an error.
This commit prevents the first line from being ignored in any case,
and allows errors to be reported consistently.

Adds support for highlighting git-status(1) output in short format
(--short) and with branch name (--branch), including file renames and
commits ahead/behind information.
Using `{\}` in an Awk script results in the following error being printed:
```
awk: cmd. line:18: warning: escape sequence `\}' treated as plain `}'
```
This commit adds a `spell_lang` option that will be used by the
`spell` command when no language is passed to it directly.
Setting a buffer/window local option allows using `:spell` seamlessly
across several buffers, written in different languages.
-verbatim will disable argument parsing in evaluate-commands, making
it possible to forward a single command to a different context without
triggering a reparsing of the arguments.
Fixes -try-client support in grep.kak
Closes#3153
When trimming indent, the last line, if only containing
whitespaces does not need to match the indent, so that
this indentation style works:
-docstring %{
indented string
}
