Add test case for merge-base. Although it was shown that the "full contamination" was not really full during the list discussion, the series improves things without incurring extra parsing cost, and here is a test to check that. Signed-off-by: Junio C Hamano <junkio@cox.net>

merge-base --independent to print reduced parent list in a merge While show-branch --independent does not support more than MAX_REVS revs, git internally supports more with a different algorithm. Expose that functionality as "git merge-base --independent". This should help scripts to catch up with builtin merge in supporting dodecapus.

git-merge-base/git-show-branch --merge-base: Documentation and test Currently, the documentation suggests that 'git merge-base -a' and 'git show-branch --merge-base' are equivalent (in fact it claims that the former cannot handle more than two revs). Alas, the handling of more than two revs is very different. Document this by tests and correct the documentation to reflect this.

merge-base --octopus: reduce the result from get_octopus_merge_bases() Scripts that use "merge-base --octopus" could do the reducing themselves, but most of them are expected to want to get the reduced results without having to do any work themselves. Tests are taken from a message by Василий Макаров <einmalfel@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com> --- We might want to vet the existing callers of the underlying get_octopus_merge_bases() and find out if _all_ of them are doing anything extra (like deduping) because the machinery can return duplicate results. And if that is the case, then we may want to move the dedupling down the callchain instead of having it here.

Add test case for merge-base. Although it was shown that the "full contamination" was not really full during the list discussion, the series improves things without incurring extra parsing cost, and here is a test to check that. Signed-off-by: Junio C Hamano <junkio@cox.net>
