Merge branch 'ab/repo-settings-cleanup' into jch
Code cleanup. * ab/repo-settings-cleanup: repository.h: don't use a mix of int and bitfields repo-settings.c: simplify the setup read-cache & fetch-negotiator: check "enum" values in switch() environment.c: remove test-specific "ignore_untracked..." variable wrapper.c: add x{un,}setenv(), and use xsetenv() in environment.c
