Fixes since v1.8.2.1
--------------------
+ * "git diff --diff-algorithm=algo" was understood by the command line
+ parser, but "git diff --diff-algorithm algo" was not.
+
+ * "git log -S/-G" started paying attention to textconv filter, but
+ there was no way to disable this. Make it honor --no-textconv
+ option.
+
+ * "git merge $(git rev-parse v1.8.2)" behaved quite differently from
+ "git merge v1.8.2", as if v1.8.2 were written as v1.8.2^0 and did
+ not pay much attention to the annotated tag payload. Make the code
+ notice the type of the tag object, in addition to the dwim_ref()
+ based classification the current code uses (i.e. the name appears
+ in refs/tags/) to decide when to special case merging of tags.
+
+ * "git cherry-pick" and "git revert" can take more than one commit
+ on the command line these days, but it was not mentioned on the usage
+ text.
+
* Perl scripts like "git-svn" closed (not redirecting to /dev/null)
the standard error stream, which is not a very smart thing to do.
Later open may return file descriptor #2 for unrelated purpose, and
