git: sh: Add UTF-8 support to pattern matching.

    sh: Add UTF-8 support to pattern matching.
    
    ?, [...] patterns match codepoints instead of bytes. They do not match
    invalid sequences. [...] patterns must not contain invalid sequences
    otherwise they will not match anything. This is so that ${var#?} removes
    the first codepoint, not the first byte, without putting UTF-8 knowledge
    into the ${var#pattern} code. However, * continues to match any string
    and an invalid sequence matches an identical invalid sequence. (This
    differs from fnmatch(3).)
