Merge branch 'en/unicode-in-refnames'

On a filesystem like HFS+, the names of the refs stored as filesystem
entities may become different from what the end-user expects, just
like files in the working tree get "renamed".  Work around the
mismatch by paying attention to the core.precomposeUnicode
configuration.

* en/unicode-in-refnames:
Honor core.precomposeUnicode in more places
