Accepting request 455466 from home:pluskalm:branches:Base:System

- Update to version 2.28:
  * Improve performance for -E or -G pattern lists that are easily
    converted to -F format.
  * Fix performance regression with multiple patterns.
  * When standard output is /dev/null, grep no longer fails when 
    standard input is a file in the Linux /proc file system, or when
    standard input is a pipe and standard output is in append mode.
  * When grep -Fo finds matches of differing length, it could
    mistakenly print a shorter one.  Now it prints a longest one.
- Drop upstreamed proc-lseek-glitch.patch
