Fixes since v1.7.5
------------------
+ * When an object "$tree:$path" does not exist, if $path does exist in the
+ subtree of $tree that corresponds to the subdirectory the user is in,
+ git now suggests using "$tree:./$path" in addition to the advice to use
+ the full path from the root of the working tree.
+
* The "--date=relative" output format used to say "X years, 12 months"
when it should have said "X+1 years".
+ * The smart-HTTP transfer was broken in 1.7.5 when the client needs
+ to issue a small POST (which uses content-length) and then a large
+ POST (which uses chunked) back to back.
+
+ * "git clean" used to fail on an empty directory that is not readable,
+ even though rmdir(2) could remove such a directory. Now we attempt it
+ as the last resort.
+
+ * The "--dirstat" option of "diff" family of commands used to totally
+ ignore a change that only rearranged lines within a file. Such a
+ change now counts as at least a minimum but non zero change.
+
+ * The "--dirstat" option of "diff" family of commands used to use the
+ pathname in the original, instead of the pathname in the result,
+ when renames are involved.
+
+ * "git pack-object" did not take core.bigfilethreashold into account
+ (unlike fast-import); now it does.
+
+ * "git reflog" ignored options like "--format=.." on the command line.
+
+ * "git stash apply" used to refuse to work if there was any change in
+ the working tree, even when the change did not overlap with the change
+ the stash recorded.
+
+ * "git stash apply @{99999}" was not diagnosed as an error, even when you
+ did not have that many stash entries.
+
* An error message from "git send-email" to diagnose a broken SMTP
connection configuration lacked a space between "hello=<smtp-domain>"
and "port=<smtp-server-port>".
