exactly, this is the bahaviour.  grep is also an interactive tool.
You want to see all lines containig foo.  -A shows you the context.

If you have a file where most lines start with `:', then
        grep -v '^:' file
shows you lines which don't start with `:'.
And -A shows you the context, ie. the syrrounding `:' lines.

The manpage explains -A that some lines after the ``matching'' ones are
printed, too.  Perhaps it would be more exact to use the word
``selected'' lines.

Have a nice day,
