bug#17246: grep-2.19 planning

[Norihiro Tanaka]

I submit a fix of the previous patch.

By the way, however, I can't understand why you adhere to keep using
egrep and/or fgrep instead of `grep -E' or `grep -F' on minor platforms
as MinGW.

Even if egrep and/or fgrep are shell scripts, they aren't troubled for
me.  Even if troubled,  I will replace them to `grep -E' and/or `grep -F'.
