v0.4.2

Fixes/support older versions

To support older versions of zsh (< 5.0.8).

We were missing the EXTENDED_GLOB option that allows use of `(#m)` flag.

This reverts commit 7f8ff286.

RHEL6 bundles v4.3.11
Ubuntu 14.04 and Amazon Linux bundle v5.0.2

v0.4.1

This fixes a small issue in src/widgets.zsh which makes it so if you
alias [ to g[ (as is done in prezto if the gnu-utility module is loaded)
autosuggestions would fail.

The documentation for GNU test mentions that -o and -a should be avoided
if possible because it's not very clear. Also, with zsh and [[ -o
actually tests if an option is set, which makes this option even more
confusing.

Now that patch has released

Use typeset -g to avoid warnnestedvar warnings

Fixes github issue #271

Simplify escaping of pattern and fix match_prev_cmd strategy

Seems like this would happen on some machines but not on others. Not
sure exactly what's going on, but this is such an edge case I'm just
going to remove the test.

https should work more broadly for folks

escape pattern-matching chars on $prefix for match_prev_cmd strategy

Maybe this is also a fix for #247, #248 and #258. Supersedes #267.

Testcase:
Using match_prev_cmd strategy and with these lines in history:
echo '1^'
echo '2^'
echo '1^'

type:
echo       (unexpected suggestion echo '1^' instead of echo '2^')
echo '1^1  (wrong suggestion echo '1^1echo '1^')
echo '1^#  (error "bad math expression")

replace tabs in Rubocop config with spaces

YAML does not permit tabs and many parsers will error when loading a tab-indented file - http://www.yaml.org/faq.html

Github #247 and #258

This commit adds the 'emacs-forward-word' widget to the list of partial
accept widgets.

Update README.md

v0.4.0

While they are still experimental

Fixes/bpm async fix

[GitHub #219]

Intended to be helpful for folks using bracketed-paste-magic and other
widgets that use `zle -U`.

Depends on patch to ZSH from workers/40702:

  http://www.zsh.org/mla/workers/2017/msg00414.html

Puts in a better fix for #126 and related issues.
