PR #776 fixed an issue with complex aliases and expansion. However, this change
also introduced a problem with aliases which contain `]` (for example, commonly
seen on macOS: `alias ]=open`), due to using an associative array `seen_alias`,
indexed by the alias name. Due to `"$seen_alias[$arg]"`, it would fail when
`$arg` is expanded to anything containing `]`'. Thus, typing `] /` would result
in:
```
> ] /
(anon):unset:3: seen_alias[]]: invalid parameter name
```
This change fixes the issue by ensuring we properly access keys in the
associative array `seen_alias`.
Older versions of zsh have issues with map keys having special
characters, especially lacking ways to remove such keys. The
issue is described in detail in
https://unix.stackexchange.com/questions/626393/in-zsh-how-do-i-unset-an-arbitrary-associative-array-element.
This fix uses proposal from
[zsh-workers/43269](https://www.zsh.org/mla/workers/2018/msg01073.html),
discovered by Stephane Chazelas, that boils down to avoid removing keys
from the map, and reconstruct the map anew with some keys omitted.

This is a regression test for a regression that was only present in development
versions of PR #764 and was never present in master.
The parent commit, which merged the feature/redrawhook bug and thereby
closed PR #749, also fixed the following issue:
Fixes#40.
Fixes#90, closes#470. (The latter is a PR for the former.)
Fixes#150, closes#151, closes#160. (The latter two are PR's for the first one.) The related issue #183 appears to have been fixed in master. For #150, a different fix for older versions of zsh was considered but has not been implemented.
Issue #154 was fixed in xsel(1) in 2017. The parent commit probably fixed that issue for pre-2017 xsel(1).
Is #245, #356, and #749. Fixes#245 (redrawhook umbrella issue).

This reverts commit 8a1bd7c8b6.
The detection only works correctly from a widget function, so the change
was wrong: it caused zsh_highlight__memo_feature to be set to false
every time.
