Merge branch 'maint-1.6.2' into maint-1.6.3

* maint-1.6.2:
base85: Make the code more obvious instead of explaining the non-obvious
base85: encode_85() does not use the decode table
base85 debug code: Fix length byte calculation
checkout -m: do not try to fall back to --merge from an unborn branch
branch: die explicitly why when calling "git branch [-a|-r] branchname".
textconv: stop leaking file descriptors
commit: --cleanup is a message option
git count-objects: handle packs bigger than 4G
t7102: make the test fail if one of its check fails
