This fixes the regression reported in [1], where Git may fail if it encounters multiple "branch." keys with no subsection, e.g. [branch ""] remote = foo merge = bar Prior to 4a2dcb1a08 (remote: die if branch is not found in repository, 2021-11-17), we silently ignored such keys. But that commit had an inconsistency in how we read and write to the branches hash map, causing us to BUG() (see Patch 1/2 for more details). This small series does two things * Fix the inconsistency in 4a2dcb1a08 that caused the bug. * Make Git fail if we find such keys (because we'll never use them anyway).
