[platform-testers] new snapshot available: grep-2.20.90-a07a4

[Jim Meyering]

Here is a third pre-release snapshot.

Since the preceding one, Norihiro Tanaka fixed a regression from
grep-2.19, and Paul Eggert made many improvements to portability, both
in grep proper, and in parts of gnulib that grep uses.  In updating to
the latest from gnulib, we have also pulled in some significant changes
to the obstack infrastructure, and grep -F uses obstacks, so for those
who find time to test, please keep an eye out for any changes.
