Make plugin work with per-directory-history too, not just global history about zsh-hist HOT 2 OPEN

The simplest implementation may be to implement an option whereby one can specify the path to an arbitrary history file (provided of course that it is a zsh-formatted/compatible history file), with HISTFILE being the default value.

from zsh-hist.

Following up: I managed to get it working with both global history ($HISTFILE) and also per-directory history by manually overriding HISTFILE when executing hist, e.g.

# delete from global history
HISTFILE="${HISTFILE}" hist delete 123  # default behavior, equivalent to just `hist delete 123`

# delete from local history
HISTFILE="${_per_directory_history_directory}" hist delete 123

_per_directory_history_directory points to my PWD-specific history file, and gets set by the per-directory-history plugin. So the code above obviously won't work in all cases.

But it illustrates a general (if hacky) approach that will work for others wanting this feature without requiring any modifications to the source code.

Ideally this feature will be implemented directly into zsh-hist, so I'll leave this issue open. But pending that, this works for me as a temporary stopgap.
