* Out of maintenance gcc on OSX 10.6 fails to compile the code in
'master'; work it around by using clang by default on the platform.
+ * The "name_path" API was an attempt to reduce the need to construct
+ the full path out of a series of path components while walking a
+ tree hierarchy, but over time made less efficient because the path
+ needs to be flattened, e.g. to be compared with another path that
+ is already flat, in many cases. The API has been removed and its
+ users have been rewritten to simplify the overall code complexity.
+ This incidentally also closes some heap-corruption holes.
+
+ * Recent versions of GNU grep is pickier than before to decide if a
+ file is "binary" and refuse to give line-oriented hits when we
+ expect it to, unless explicitly told with "-a" option. As our
+ scripted Porcelains use sane_grep wrapper for line-oriented data,
+ even when the line may contain non-ASCII payload we took from
+ end-user data, use "grep -a" to implement sane_grep wrapper when
+ using an implementation of "grep" that takes the "-a" option.
