Bug#406259: { echo foo; echo bar; } |grep -o ^. matches every letter

[Justin Pryzby]

Package: grep
Version: 2.5.1.ds2-6

$ { echo foo; echo bar; } |grep -o ^.
f
o
o
b
a
r

This can't be right, since only the first character of a line should
match (and only if the line is not blank).  I expect to see just:
f
b
