Thank you, Jeff, for explaining my misunderstanding and how to fix it.
Would it be safe to ask the maintainer of the application to include both --textconv and --ext-diff in that 'git diff-tree' call? I only need the latter, but someone needed --textconv there as it's in the code.
This is for this package: https://github.com/rsmmr/git-notifier
It was added here: https://github.com/rsmmr/git-notifier/search?q=textconv&unscoped_q=textconv
