+For folks that want to start versioning a new tag-space, instead of\r
+cloning one that someone else has already started.\r
+\r
+The empty-blob hash-object call avoids errors like:\r
+\r
+ $ nmbug commit\r
+ error: invalid object 100644 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 for\r
+'tags/...'\r
+ fatal: git-write-tree: error building trees\r
+ 'git HASH(0x9ef3eb8) write-tree' exited with nonzero value\r
+\r
+David Bremner suggested [1]:\r
+\r
+ $ git hash-object -w /dev/null\r
+\r
+instead of my Python version of:\r
+\r
+ $ git hash-object -w --stdin <&-\r
+\r
+but I expect that closing stdin is more portable than the /dev/null\r
+path (which doesn't exist on Windows, for example).\r

+ http://thread.gmane.org/gmane.mail.notmuch.general/18626/focus=18720\r
+---\r
+The only change since v2 [1] is a commit-message tweak:\r
+\r
+* Mention Windows as an OS with stdin but no /dev/null [2].\r
