Post version pages are used for showing a post's, a person's or a tag's tag history.
Some tags are too long, e.g. guild_no_uketsukejou_desu_ga_zangyou_wa_iya_nanode_boss_wo_solo_toubatsu_shiyou_to_omoimasu is way too long, and it makes the edits column too narrow, I can't see my post history or the post history for that this tag's pictures. Also on post history it makes the image hidden (???)
E.g.
random picture with that copyright: https://danbooru.donmai.us/post_versions?search[post_id]=9066712
random other picture: https://danbooru.donmai.us/post_versions?search[post_id]=8281371
I believe that the tools are already there, long URLs don't cause any problems, whatever chops up the URLs could be used to chop up long-ass tags.
Additionally "Edits" is the most important column there, so all the other columns just saying "Source" or "Revert it" could be narrower.
