 DESCRIPTION
 -----------
 
-Prepare each commit between <since> and <until> with its patch in
+Prepare each commit with its patch in
 one file per commit, formatted to resemble UNIX mailbox format.
-If ..<until> is not specified, the head of the current working
-tree is implied.  For a more complete list of ways to spell
-<since> and <until>, see "SPECIFYING REVISIONS" section in
-gitlink:git-rev-parse[1].
-
 The output of this command is convenient for e-mail submission or
 for use with gitlink:git-am[1].
 
+There are two ways to specify which commits to operate on.
+
+1. A single commit, <since>, specifies that the commits leading
+   to the tip of the current branch that are not in the history
+   that leads to the <since> to be output.
+
+2. Generic <revision range> expression (see "SPECIFYING
+   REVISIONS" section in gitlink:git-rev-parse[1]) means the
+   commits in the specified range.  A single commit, when
+   interpreted as a <revision range> expression, means
+   "everything that leads to that commit", but that is taken as
+   the special case above.  If you want to format everything
+   since project inception to one commit, say "git format-patch
+   \--root <that-commit>", as showing the root commit as patch
+   requires \--root option anyway.
+
 By default, each output file is numbered sequentially from 1, and uses the
 first line of the commit message (massaged for pathname safety) as
 the filename. With the --numbered-files option, the output file names
