Author: emaste Date: Mon Sep 11 00:14:04 2017 New Revision: 323405 URL: https://svnweb.freebsd.org/changeset/base/323405 Log: newvers.sh: speed up failing git-svn revision search In the case of running newvers.sh on a git tree w/o git-svn-id notes we previously piped the entire 'git log' to grep. Add --grep to the log invocation to avoid processing log entries of no interest. This saves about 2-3 seconds of newvers.sh run time on my SSD laptop. Later changes will bring further speedups.
