"git push" and "git fetch" reports from what old object to what new object each ref was updated, using abbreviated refnames, and they attempt to align the columns for this and other pieces of information. The way these codepaths compute how many display columns to allocate for the object names portion of this output has been updated to match the recent "auto scale the default abbreviation length" change. * jc/abbrev-auto: transport: compute summary-width dynamically transport: allow summary-width to be computed dynamically fetch: pass summary_width down the callchain transport: pass summary_width down the callchain
