[bug#42093] [PATCH 1/2] gnu: emacs-nov-el: Use version tag instead of commit.

[Simon South <simon@simonsouth.net>]

* gnu/packages/emacs-xyz.scm (emacs-nov-el): Remove let binding and associated
comment; correct indentation.
[source]: Use version tag as commit identifier now that upstream has restored
this information.
