* `git_buf_rfind` (with tests and tests for `git_buf_rfind_next`)

  (e.g. '\') in front of particular characters.

examples: add README

Bring back `entry_bypath`

diff: make inter-hunk-context default value git-compliant

Point to the libgit2-glib wiki page

Fix libgit2 on GNU/Hurd.

On GNU, the d_name field of the dirent structure is defined as "char d_name[1]",
so we must allocate more than sizeof(struct dirent) bytes, just like on Sun.

revparse: fix parsing of date specifiers

Replace incorrect 'it' with 'if' in documentation

Default in git core is 0, not 3

More git_revparse_single ENOTFOUND use cases

It causes the clar testsuite to abort on Windows, and isn't necessary.

Smaller, simpler, faster.

Small revparse colon syntax improvements

Once a file is registered, there is no way to deregister it, even
after the structure that contains it is no longer needed and has been
freed. This may be the source of #624.

Allow and use the deregister function to remove our file from the
global list.

indexer: don't use '/objects/pack/' unconditionally

Not everyone who indexes a packfile wants to put it in the standard
git repository location.

Repo reinit fix + enhanced test coverage

indexer: start parsing input data immediately

Currently, the first call of git_indexer_stream_add adds the data to the
underlying pack file and opens it for later use, but doesn't start
parsing the already available data.
This means, git_indexer_stream_finalize only works if
git_indexer_stream_add was called at least twice. Kill this limitation
by parsing available data immediately.
