Andrew Janke 45822e85c5 history-substring-search: bind arrows in both emacs and viins modes
This avoids an ordering dependency between this and the vi-mode plugin.

#
# This script updates the Oh My Zsh version of the zsh-history-substring-search
# plugin from the independent upstream repo. This is to be run by OMZ developers
# when they want to pull in new changes from upstream to OMZ. It is not run
# during normal use of the plugin.
#
# The official upstream repo is zsh-users/zsh-history-substring-search
# https://github.com/zsh-users/zsh-history-substring-search
#
# This is a zsh script, not a function. Call it with `zsh update-from-upstream.zsh`
# from the command line, running it from within the plugin directory.
#
# You can set the environment variable REPO_PATH to point it at an upstream
# repo you have already prepared. Otherwise, it will do a clean checkout of
# upstream's HEAD to a temporary local repo and use that.
# Just bail on any error so we don't have to do extra checking.
# This is a developer-use script, so terse output like that should
# be fine.

Oh My Zsh Distribution Notes
$thin_line
What you are looking at now is Oh My Zsh's repackaging of zsh-history-substring-search
as an OMZ module inside the Oh My Zsh distribution.
The upstream repo, $UPSTREAM_REPO, can be found on GitHub at
$upstream_github_url.
This downstream copy was last updated from the following upstream commit:
SHA: $upstream_sha
Commit date: $upstream_commit_date
Everything above this section is a copy of the original upstream's README, so things
may differ slightly when you're using this inside OMZ. In particular, you do not
need to set up key bindings for the up and down arrows yourself in \`~/.zshrc\`; the OMZ
plugin does that for you. You may still want to set up additional emacs- or vi-specific
bindings as mentioned above.
