update_unicode.sh: move it into contrib/update-unicode

As it's used only by a tiny minority of the Git developer population, this script does not belong into the main Git source directory. Move it into contrib/ and adjust the paths to account for the new location. Signed-off-by: Beat Bolli <dev+git@drbeat.li> Signed-off-by: Junio C Hamano <gitster@pobox.com>

1 +TL;DR: Run update_unicode.sh after the publication of a new Unicode
2 +standard and commit the resulting unicode_widths.h file.
3 +
4 +The long version
5 +================
6 +
7 +The Git source code ships the file unicode_widths.h which contains
8 +tables of zero and double width Unicode code points, respectively.
9 +These tables are generated using update_unicode.sh in this directory.
10 +update_unicode.sh itself uses a third-party tool, uniset, to query two
11 +Unicode data files for the interesting code points.
12 +
13 +On first run, update_unicode.sh clones uniset from Github and builds it.
14 +This requires a current-ish version of autoconf (2.69 works per December
15 +2016).
16 +
17 +On each run, update_unicode.sh checks whether more recent Unicode data
18 +files are available from the Unicode consortium, and rebuilds the header
19 +unicode_widths.h with the new data. The new header can then be
20 +committed.
