Fixes since v1.5.6.4
--------------------
+* "git cvsimport" used to spit out "UNKNOWN LINE..." diagnostics to stdout.
+
* "git init --template=" with blank "template" parameter linked files
under root directories to .git, which was a total nonsense. Instead, it
means "I do not want to use anything from the template directory".
+* "git diff-tree" and other diff plumbing ignored diff.renamelimit configuration
+ variable when the user explicitly asked for rename detection.
+
+* "git name-rev --name-only" did not work when "--stdin" option was in effect.
+
* "git show-branch" mishandled its 8th branch.
* Addition of "git update-index --ignore-submodules" that happened during
header properly.
Contains other various documentation fixes.
