+ This can only resolve two heads (i.e. the current branch
+ and another branch you pulled from) using 3-way merge
+ algorithm. It tries to carefully detect criss-cross
+ merge ambiguities and is considered generally safe and
+ fast. This is the default merge strategy when pulling
+ one branch.
+ This can only resolve two heads using 3-way merge
+ algorithm. When there are more than one common
+ ancestors that can be used for 3-way merge, it creates a
+ merged tree of the common ancestores and uses that as
+ the reference tree for the 3-way merge. This has been
+ reported to result in fewer merge conflicts without
+ causing mis-merges by tests done on actual merge commits
+ taken from Linux 2.6 kernel development history.
+ Additionally this can detect and handle merges involving
+ renames.
+ This resolves more than two-head case, but refuses to do
+ complex merge that needs manual resolution. It is
+ primarily meant to be used for bundling topic branch
+ heads together. This is the default merge strategy when
+ pulling more than one branch.
+ This resolves any number of heads, but the result of the
+ merge is always the current branch head. It is meant to
+ be used to supersede old development history of side
+ branches.
