config: learn the "onbranch:" includeIf condition
Currently, if a user wishes to have individual settings per branch, they
are required to manually keep track of the settings in their head and
manually set the options on the command-line or change the config at
each branch.
Teach config the "onbranch:" includeIf condition so that it can
conditionally include configuration files if the branch that is checked
out in the current worktree matches the pattern given.
