From 801d6cc7532a6f419c3553c4180820db6540f263 Mon Sep 17 00:00:00 2001
From: Christopher Faylor <me@cgf.cx>

Subject: * strace.cc (show_usecs): Renamed from 'usecs'. (main): Use
 show_usecs rather than usecs.  Toggle delta if '-u' is specified.
 (handle_output_debug_string): Avoid printing microsecond timestamp if
 show_usecs == 0. * utils.sgml (strace): Add words to describe '-u'.
