Dustin SallingsChange cd67e4d4 introduced a new configuration parameter that told pull to automatically perform a rebase instead of a merge. I use this feature quite a bit in topic branches and would like it to be the default behavior for a topic branch.
If the parameter branch.autosetuprebase applies for a branch that's being created, that branch will have branch.<name>.rebase set to true.
See the documentation for how this may be applied.
