Lisp error: (void-variable age-default-identity) in chezmoi-ediff

[joelpet]

After upgrading chezmoi.el from 8a4d683 to 1389782, I started encountering the following error:

Debugger entered--Lisp error: (void-variable age-default-identity)
  chezmoi-ediff("~/.emacs.d/straight/repos/straight.el/install.el")
  funcall-interactively(chezmoi-ediff "~/.emacs.d/straight/repos/straight.el/install.el")
  call-interactively(chezmoi-ediff nil nil)
  command-execute(chezmoi-ediff)

This error occurs after invoking chezmoi-ediff and selecting a file.

Here is a condensed version of the relevant part of my configuration:

(use-package chezmoi
  :straight (chezmoi :files (:defaults "extensions/chezmoi-ediff.el"
                                       "extensions/chezmoi-magit.el")))

(use-package chezmoi-ediff
  :straight nil ; part of chezmoi
  :bind
  ("<leader> f d e" ("Ediff…" . chezmoi-ediff)))

(use-package chezmoi-magit
  :straight nil ; part of chezmoi
  :bind
  ("<leader> f d g" ("Magit status" . chezmoi-magit-status)))

Here is the pertinent code from chezmoi-ediff.el:

(age-always-use-default-keys (and (equal ident age-default-identity)
					   (equal (if (equal 1 (length recips))
						      (car recips)
						    recips)
						  age-default-recipient)))

The age-default-identity symbol is defined as a customizable variable over at github.com/anticomputer/age.el#L82, but age.el is never required by chezmoi-ediff.el.
