"git status" has trouble showing where it came from by interpreting reflog entries that recordcertain events, e.g. "checkout @{u}", and gives a hard/fatal error. Even though it inherently is impossible to give a correct answer because the reflog entries lose some information (e.g. "@{u}" does not record what branch the user was on hence which branch 'the upstream' needs to be computed, and even if the record were available, the relationship between branches may have changed), at least hide the error to allow "status" show its output. * jt/interpret-branch-name-fallback: wt-status: tolerate dangling marks refs: move dwim_ref() to header file sha1-name: replace unsigned int with option struct
