From 96e9420cd357728949571b42eb0249881ae3a78e Mon Sep 17 00:00:00 2001 From: Ramkumar Ramachandra Date: Wed, 8 Sep 2010 23:29:54 +0530 Subject: [PATCH] merge: Make '--log' an integer option for number of shortlog entries Change the command-line '--log' option from a boolean option to an integer option, and parse the optional integer provided on the command-line into the 'shortlog_len' variable. Also update the documentation accordingly.
