Set ZSH_AUTOSUGGEST_STRATEGY to choose the strategy for generating suggestions.
There are currently two to choose from:
* history: Chooses the most recent match.
* match_prev_cmd: Chooses the most recent match whose preceding history item matches
the most recently executed command (more info). Note that this strategy won't work as
expected with ZSH options that don't preserve the history order such as
HIST_IGNORE_ALL_DUPS or HIST_EXPIRE_DUPS_FIRST.
