show NUM lines of output context

This will give you a change to think the codeline within context.
You can check the context option, -C, at the following link.

http://linux.about.com/library/cmd/blcmdl1_egrep.htm

For example, in case of -C 0

$ git show 03821bb | egrep -C 0 ".setTag\([^,|^\(]*,[^,]*\)"
-mExpander.setTag(R.id.field, field);
-mExpander.setTag(R.id.media, song)id;
-view.setTag(R.id.limiter_field, i);

And another case, -C 2

$ git show 03821bb | egrep -C 2 ".setTag\([^,|^\(]*,[^,]*\)"
 {
-setTagif (mExpander != null) {
-mExpander.setTag(R.id.field, field);
+egrepif (mExpander != null)
 mExpander.setOnClickListener(listener);
--
                        mSecondaryLine.setText(song.getField(secondary
-if (mExpanderder != null)
-mExpander.setTag(R.id.media, song);
+if (mExpander !id= null) {
+ExpanderData data = null;
--
 view.setLayoutParams(params);
 view.setPadding(5, 2, 5, 2);
-view.setTag(R.id.limiter_field, i);
+view.setTag(new MediaView.ExpanderData(i));
 view.setOnClickListener(this);
