 *Git/Mercurial/Svn* workspace (note *--diff* option is new in svn 1.7.0):
 
 .. code:: sh
     cdiff -l

-    diff -ur dir1 dir2 | cdiff  # read diff of two dirs
-
-View a diff (patch) file:
-
-.. code:: sh
-
-    cdiff < foo.patch           # or cat foo.patch | cdiff
-    cdiff -s < foo.patch
-    cdiff -s -w 90 < foo.patch
+    git log -p -2 | cdiff -s    # view git log with changes of last 2 commits
+    git show 15bfa | cdiff -s   # view a git commit
+    svn diff -r1234 | cdiff -s  # view svn diff comparing to given revision
+    cdiff < foo.patch           # view a patch file (unified format only)
+    cat foo.patch | cdiff       # same as above
+    diff -u foo bar | cdiff     # pipe in diff between two files (note the '-u')
+    diff -ur dir1 dir2 | cdiff  # pipe in diff between two dirs
 
 Redirect output to another patch file is safe:
