svn commit: r202148 - user/ed/utmpx/lib/libc/gen

[Ed Schouten]

New Revision: 202148
URL: http://svn.freebsd.org/changeset/base/202148

Log:
  Fix an off-by-one introduced in the previous commit.
  
  When receiving a partial match, we should overwrite the record itself.
  Because we call lseek() afterwards, we get the offset of the next to it.
