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.

Using `{\}` in an Awk script results in the following error being printed:
```
awk: cmd. line:18: warning: escape sequence `\}' treated as plain `}'
```
Previously, the keywords were a mess. They contained the shell’s
reserved words and some arbitrarily selected builtins. I generated
the word list using bash because it contains all POSIX builtins and
is common for scripting.
In variable assignments some characters that are allowed to be in
variables used to not be highlighted, e.g. hyphens. With this commit
all characters except whitespace are considered to be part of the
variable.
This commit implements a standalone shared highlighter group that
highlights Jinja statements and expressions.
The traditional way of highlighting file contents is to hook on the
file extension, and assign a custom filetype/highlighter group to
the current buffer. However, since Jinja templates can be based on
any text file format in existence, we do not have a specific file
extension to hook, and consequently, no custom "jinja" filetype.
The user is expected to add the `jinja` highlighter whenever required:
```
require-module jinja
add-highlighter window/ ref jinja
```
Alternatively, file extensions that are known to occasionally pair
with Jinja can be hooked from the user configuration:
```
hook global WinCreate .+\.html %[
try %[
execute-keys -draft \%s \{%|\{\{ <ret>
require-module jinja
add-highlighter window/ ref jinja
]
]
```
The above hook auto-detects statements/expressions (respectively
{%…%} and {{…}} expansions), but will cause false positives
(in terms of highlighting), and therefore isn't part of `jinja.kak`
by default.
This commit removes attempts to auto-detect the version of the local
Tmux binary.
The Tmux package that ships with OpenBSD doesn't have a version
number[1], and therefore doesn't provide any way to check if it's
compatible with the REPL module, making the feature disabled by
default in that distribution.
Fixes#3237.

The `pick` command in a rebase commit is virtually a no-op, but other
commands actually do things. This commit visually communicates
that fact.
Fixes#3208.
