New Revision: 255135
URL: http://svnweb.freebsd.org/changeset/base/255135
Log:
Use single underscore for all parameters name and local variables in
bintime_* related functions. This commit completes what was already done
by theraven@ for bintime_shift, and just uses a single underscore instead
of two (which is a style bug according to Bruce). See r251855 for reference.
