stream-clone-test: add title to various test cases

These case are fine as is, but as we are adding title to all the other as we
simplify them, lets add title for all cases.

= Mercurial 6.7rc0 =

/!\ These are **tentative** release notes for the upcoming Mercurial 6.7.
Anything can be added or removed before the actual release.

As usual, a *lot* of patches don't make it to this list.

== New Features ==

 * JSON templates can now use structured diffstat data
 * Support rhg status --rev --rev
 * The index for REVLOGv1 now has a Rust implementation
 * Improved `hg censor`'s output
 * censor: add a command flag to skip the head checks
 * censor: accept multiple revision in a single call
 * usage: add a `usage.repository-role` config
 * branchmap: use mmap for faster revbranchcache loading
 * crecord: enable search hotkeys (issue6834)
 * hg-core: separate timestamp and extra methods
 * annotate: limit output to range of lines
 * unbundle: faster computation of changed heads
 * Large improvements of some of the phases code (23950e39281f)

== New Experimental Features ==

 * Introduce `hg admin::chainsaw-update` for automation and *advanced* users

== Bug Fixes ==

 * templatekw: fix inconsistency of diffstat with diff.merge
 * The endless stream of Python 3 cleanups continues
 * Improved setup.py robustness
 * Improved test suite robustness
 * add: don't attempt to add back removed files unless explicitly listed
 * statprof: handle `lineno == None` in more cases
 * rust: fix cargo doc for hg-cpython
 * rust-python-index: don't panic on a corrupted index when calling from Python
 * debugindexstats: handle the lack of Rust support better
 * matchers: use correct method for finding index in vector
 * narrow: strip trailing `/` from manifest dir before matching it
 * cext: fix potential memory leaks of list items appended with PyList_Append
 * doc: document that labels must have a dot in them to have an effect
 * debugformat: fix formatting for compression level

== Backwards Compatibility Changes ==

Users of the Rust extensions and/or `rhg` should be aware that the new Rust
index can result in a performance degradation for push/pull on repositories
*not* using `persistent-nodemap` (see `hg help config.format.use-persistent-nodemap`).

If this is something that matters to you, please reach out to us as this is not
an insurmountable obstacle. This is a choice base on the assumption that
there are few people in this situation and our time should be spent on more
pressing matters.
