Thanks for continuing to push on this. This looks good so far (to me), but I was also hoping to see the analogy between these messages and "Auto-merging $FILE" for regular files mentioned. Both Junio[1] and I[2] pointed out this similarity, and I think this similarity/analogy is useful additional motivation for making this change. [1] https://public-inbox.org/git/xmqqo9hg7554.fsf@xxxxxxxxxxxxxxxxxxxxxxxxx/ [2] https://public-inbox.org/git/CABPp-BGaibCPWuCnaX5Af=sv-2zvyhNcupT+-PkxHDfJBg_Vbw@xxxxxxxxxxxxxx/ > + } else if (show(o, 2)) > + output(o, 2, _("Fast-forwarding submodule %s to %s"), path, oid_to_hex(b)); ... > + } else if (show(o, 2)) > + output(o, 2, _("Fast-forwarding submodule %s to %s"), path, oid_to_hex(a)); Also, by analogy to the "Auto-merging $FILE" comparison, the "to %s" on these two lines feels out of place. Users can just look at the submodule to see what it was updated to. In a sea of output from merging, this extra detail feels like noise for the standard use-case, unless I'm misunderstanding how submodules are special. Junio also commented on this in the same email referenced above (at [1]). Is there a reason this is an important piece of the message for you to be shown at the standard merge verbosity?
