[platform-testers] new snapshot available: grep-2.11.11-b00d1

[Jim Meyering]

In spite of the small number of changes, we're ready for a release.
The combination of Allan McRae's segfault fix and Paul Eggert's
change to make grep's -r/-R use gnulib's fts for hierarchy traversal
make this a good time for a point release.

So here's the latest.
I'm aiming for a release early next week.
