When we update the current branch, we must also append to HEAD's reflog
to keep them in sync.
This is a bit of a hack, but as git.git says, it covers 100% of
default cases.
This is not something anybody would ever do; removing HEAD makes the
.git/ directory no longer be a repository, so we wouldn't be expected to
handle such a situation.
* Make GIT_INLINE an internal definition so it cannot be used in
public headers
* Fix language in CONTRIBUTING
* Make index caps API use signed instead of unsigned values
This fixes a number of warnings with the Windows 64-bit build
including a test failure in test_repo_message__message where an
invalid pointer to a git_buf was being used.
Any well-behaved program should write a descriptive message to the
reflog whenever it updates a reference. Let's make this more prominent
by removing the version without the reflog parameters.
