Merge branch 'maint'

* maint:
t1301-shared-repo.sh: don't let a default ACL interfere with the test
git-check-attr(1): add output and example sections
xdiff-interface.c: strip newline (and cr) from line before pattern matching
t4018-diff-funcname: demonstrate end of line funcname matching flaw
t4018-diff-funcname: rework negated last expression test
Typo "does not exists" when git remote update remote.
remote.c: correct the check for a leading '/' in a remote name
Add testcase to ensure merging an early part of a branch is done properly
