+* Decide the notation of "peeling the onion" operator, and
+ implement it in sha1_name.c. Perhaps postfix "^{}" to mean
+ "peel and expect anything", "^{blob}" to mean "peel and barf
+ unless blob". The current "^0" becomes shorthand for
+ "^{commit}". [DONE]
+
+* Quote the URL so that libcurl's metecharacter mechanism would
+ not kick in [DONE].
+
+* Review the Makefile variables and exporting rules for them,
+ while looking at prefix passing by Kai Ruemmler [DONE].
+
+* Review the 'sparse object database' change by Linus and move
+ the first phase of it to the "master" branch [DONE].
+
+* Decide on mmap(). I am inclined to just stick to mmap
+ replacement by Johannes Schindelin and do nothing else right
+ now, except perhaps drop the writing-back support [DONE].
