I've run into change ID prefixes being 4-5 characters instead of the usual 1-2 characters in commands like
jj duplicate
andjj split
fairly often, and it seems like this should resolve that. I tried to avoid creating a newIdPrefixContext
unless changes have already been made in the transaction, since several commands calltx.format_commit_summary()
before making any changes.Checklist
