But that's better than having +# two files (both 'a' and 'a2') sitting around without the user being notified +# that we could detect they were related and need to be merged. Also, choice +# 5 makes the handling of 'a/file' seem suboptimal. What if we were to merge +# D2 and E4, where D2 is: +# Commit D2: Merge B & C, renaming 'a'->'a2', keeping 'a/file' +# This would result in a clean merge with 'a2' having three-way merged +# contents (good), and deleting 'a/' (bad) -- it doesn't detect the +# conflict in how the different sides treated a/file differently. +# Continuing down the creative route: +# 6: Keep 'a' as 'a~$UNIQUE1' and keep 'a/' as 'a~$UNIQUE2/'; results: +# Merge D1 & E1: rename/delete conflict for 'a' and each path under 'a/'. +# Merge D1 & E3: clean, as expected. +# Merge D1 & E4: rename/rename(1to2) conflict on 'a' vs 'a2'. +# Merge D2 & E4: clean for 'a2', rename/delete for a/file +# +# Choice 6 could cause rename detection to take longer (providing more targets +# that need to be searched).
