That is why I use format: (not tformat:) there. Ah. I would have expected whatever you pulled the output into to eat the newline. But there is no point in nitpicking, as this is a personal alias.

Actually, there is one spot missing from my previous patch. Rev-list sets "save_commit_buffer" based on the value of grep_filter. So it must also check grep_filter->pattern_list. > As you suggested, making the grep option structure embedded in rev_info > may not be a bad idea.

I worked up this patch, and it is below. However, I think it may not be a good idea, because... > The only issue I still have, which I suspect your fix has made it easier > to address, is to complain if sub-options to grep like -i and -E are given > without --grep. That's not something v1.5.6 series did, though. This is trivial with my first patch, but not with the second. With grep_filter kept as a pointer, we know that if the pointer is non-NULL but there are no patterns, then the user asked for grep options but never --grep. I guess this might be a helpful thing for some users, but I wonder if it is being too unpredictable for script usage. I.e., a script like: git log -E `for i in "$@"; do echo --author=$i` Anyway, the non-allocating patch is below. Aside from the test case, it deletes more lines than it adds, which is always nice. -- >8 -- fix "git log -i --grep" This has been broken in v1.6.0 due to the reorganization of the revision option parsing code. The "-i" is completely ignored, but works fine in "git log --grep -i". What happens is that the code for "-i" looks for revs->grep_filter; if it is NULL, we do nothing, since there are no grep filters. But that is obviously not correct, since we want it to influence the later --grep option. Doing it the other way around works, since "-i" just impacts the existing grep_filter option. Instead, we now always initialize the grep_filter member and just fill in options and patterns as we get them. This means that we can no longer check grep_filter for NULL, but instead must check the pattern list to see if we have any actual patterns.
