[PATCH 1/1] reset: parse rev as tree-ish in patch mode

["Nika Layzell via GitGitGadget" <gitgitgadget@gmail.com>]

From: Nika Layzell <nika@thelayzells.com>

Relaxes the commit requirement for the rev argument when running
git-reset in patch mode without pathspec.

The revision argument to git-reset is parsed as either a commit or
tree-ish depending on mode. Previously, if no pathspec was provided,
the rev argument was parsed as a commit unconditionally.
