grep bug

A problem recently came to light about grep.  Try this
to reproduce:

$ echo '1.1.1.2
123.123.123.2 is different than 321.123.321.1 so there
no ip here
0.0.0.0
bye' > grep-test-file1

$ touch grep-test-file2

$ egrep -Ho '([0-9]{1,3}\.){3}[0-9]{1,3}' grep-test-file1 grep-test-file2
grep-test-file1:1.1.1.2
grep-test-file1:123.123.123.2
321.123.321.1
grep-test-file1:0.0.0.0

$

Now the man and info pages state that the "-H" option is supposed
to "Print the filename for each match."  Clearly this is not
happening with multiple matches per line.

It seems to me that either grep or the documentation needs updating.
