Subject: Re: [PATCH v2 3/8] fetch: fix missing from-reference when fetching HEAD:foo
Date: Thu, 27 Apr 2023 10:26:38 -0700 [thread overview]
Message-ID: <kl6lo7n9me29.fsf@chooglen-macbookpro.roam.corp.google.com> (raw)

For v2, I've only read through this patch for now. I'm still formulating
my thoughts on the output format and the CLI option name.

This rewritten section explains the bug and the fix very nicely :)
Thanks!

Maybe rename the test to just 'fetch output with HEAD'? The 'and
--dry-run' part seems completely obsolete.
