[PATCH 1/2] Rewrite man page explanation of git log's "--log-size" option

["Jason St. John" <jstjohn@purdue.edu>]

Documentation/git-log.txt:
--log-size was added in commit 9fa3465, and the commit message contained
a satisfactory explanation; however, the man page entry for it was
unclear and cryptic.

Thanks-to: Jonathan Nieder <jrnieder@gmail.com>

 --log-size::
-	Before the log message print out its size in bytes. Intended
-	mainly for porcelain tools consumption. If Git is unable to
-	produce a valid value size is set to zero.
-	Note that only message is considered, if also a diff is shown
-	its size is not included.
+
+	Include a line ``log size <number>'' in the output for each commit,
+	where <number> is the length of that commit's message in bytes.
+	Intended to speed up tools that read log messages from `git log`
+	output by allowing them to allocate space in advance.
