Wow, blast from the past. Those column width tweaks in blame output were my very first patches for SVN, over 15 years ago: - Aligning in case of high revision numbers (actually Julian Foad did all the hard work there): https://svn.apache.org/viewvc/?revision=955895&view=revision - Truncating long author names (a patch of 3 characters): https://svn.apache.org/viewvc/?revision=957874&view=revision Actually, in the referenced discussion Brane suggested that blame should truncate author names just like 'svn ls' does [1] :-). Seems that has changed later for 'ls' then. Oh well ... On rereading that old thread it's nice to see how friendly the experienced devs were to a newbie like me, and how they gently reeled me to make my first baby steps with this micro-bug :-).
