Teach grep to recursively search in submodules when provided with a
<tree> object. This allows grep to search a submodule based on the state
of the submodule that is present in a commit of the super project.
When grep is provided with a <tree> object, the name of the object is
prefixed to all output. In order to provide uniformity of output
between the parent and child processes the option `--parent-basename`
has been added so that the child can preface all of it's output with the
name of the parent's object instead of the name of the commit SHA1 of
the submodule. This changes output from the command
`git grep -e. -l --recurse-submodules HEAD` from:
HEAD:file
<commit sha1 of submodule>:sub/file
to:
HEAD:file
HEAD:sub/file
