The extra lines _are_ a disadvantage for me, since each chunk gets them while only close ones need them -- that's wasted space. The intent is to save time by not having to apply and rediff a patch on a mailing list in order to see the hidden text; part of the savings would be lost if the reader had to skip over extra lines. Besides, this option is probably most useful if set by default on machines not controlled by me. E.g. I wouldn't want to change an option on a gitweb page, I'd want to get fused chunks by default. I wouldn't want to write "best viewed with -U6" in a patch description, I'd want it to just work (e.g. for gitk users). I have to admit my main motivation was that one line gap, where a chunk header hid an interesting line of context. Showing it didn't change the length of the patch, so I found this to be a sad wastage. Optimizing patches for readability makes sense since they are such an important part of our communication here. I think --i-c-c=1 results in an obvious win without much of a downside. I was surprised to find that almost 4% of the chunks in git 1.6.0 would be eliminated by that option: $ git log -p v1.6.0 | grep -c '^@@ ' 60544 $ git log -p v1.6.0 --inter-chunk-context=1 | grep -c '^@@ ' 58471 But perhaps a higher value would be even better? $ git log v1.6.0 | wc -l 225441 $ git log -p v1.6.0 | wc -l 1736188 $ git log -p --inter-chunk-context=10 v1.6.0 | wc -l 1779048 $ git log -p -U8 v1.6.0 | wc -l 2214448 Well, I don't know if those patches are easier to read (haven't looked at them), but I imagine that some related changes are presented with the full context between them (e.g. changes to loop header and footer, function signature and body). The numbers only show that it's affordable (3% more lines with -i-c-c=10, 30% more lines with the comparable -U8). (Why 10? With the default of -U3, a chunk is 6 lines of context plus at least one line of actual change. Two chunks are at least 14 lines long, thus only 10 more fit into 24 lines, i.e. a terminal window..)
