utf8.c: partially update to version 6.3
Unicode 6.3 defines more code points as combining or accents. For
example, the character "ö" could be expressed as an "o" followed by
U+0308 COMBINING DIARESIS (aka umlaut, double-dot-above). We should
consider that such a sequence of two codepoints occupies one display
column for the alignment purposes, and for that, git_wcwidth()
should return 0 for them. Affected codepoints are:
U+0358..U+035C
U+0487
U+05A2, U+05BA, U+05C5, U+05C7
U+0604, U+0616..U+061A, U+0659..U+065F
Earlier unicode standards had defined these as "reserved".
Only the range 0..U+07FF has been checked to see which codepoints
need to be marked as 0-width while preparing for this commit; more
updates may be needed.
