Fixeszsh-users/zsh-syntax-highlighting#188 in the case that both the
opening '((' and closing '))' have been typed, The case that only the
opening '((' have been typed is also fixed, but requires a zsh development
build (zsh-5.1.1-52-g4bed2cf or newer); see comments within.
Without this, redirections, history expansions, and command separators would
be matched by path_approx.
A test case is simply LBUFFER="<" RBUFFER="" (highlighted as redirection with this
fix and as path_approx without it).
Fixeszsh-users/zsh-syntax-highlighting#204.
Highlight the last character of a «\xHH» escape when it is the last thing in
LBUFFER. This is similar to what b0cc02ed86e3586ab92cc1082fb97b94cd5f584f did
for issue #186.
Correct highlighting of backslash escapes within "" strings: highlight only
the four specific escape sequences defined there.
Fixeszsh-users/zsh-syntax-highlighting#196.
This was broken by c2b9327b0763f3457fb09db17e22ee9e1e024792
and tracked as zsh-users/zsh-syntax-highlighting#199.
This fixes the vanilla-newline.zsh test, which was was (consciously) broken
by the previous commit.
'local' is a reserved word in zsh 5.1 but not in earlier versions [1].
Therefore, under zsh older than 5.1, quoting is required.
This manifested as random «builtin=''» in emitted to the terminal, and
commands (such as 'echo') highlighted as errors (in red).

(the section "Incompatibilites between 5.0.8 and 5.1")
Given the following input:
PREBUFFER=$'echo "foo\n'
BUFFER='bar"'
This patch causes the '"foo' part to be highlighted as a string. There
is no test because the tests only check highlighting of BUFFER, and 'bar"'
is already highlighted correctly.
If one defines aliases like `++` the alias builtin tries to interprete these
as options so they have to be protected like this
alias -- ++=true
The same goes for a call to `alias` in order to expand the alias again.
This code is more lenient than bash. Examples:
$ x[y[]=
zsh: no matches found: x[y[]=
$ x[][]=
zsh: no matches found: x[][]=
The proper solution is to look inside the [...] and make sure that all
unescaped/unquoted square brackes are matched, but that is a heck of
a lot more complicated than this simple 8-character patch.
Zsh does not allow the variable name or the equals sign to be quoted or
escaped. The previous code incorrectly highlighted the following
examples as assignments:
$ 'x=y'
zsh: command not found: x=y
$ x\=y
zsh: command not found: x=y
$ "x"=y
zsh: command not found: x=y
$ \x=y
zsh: command not found: x=y
