Merge branch 'cc/shared-index-permbits'

gitster · gitster · commit 9fc9555312ea · 2018-11-21T20:39:03.000+09:00
The way .git/index and .git/sharedindex* files were initially
created gave these files different perm bits until they were
adjusted for shared repository settings.  This was made consistent.
