Better Highlighting of Find's Results in the Terminal

[justinfargnoli]

When using Find in the integrated Terminal it has been challenging for me to see what is being highlighted because it blends in with the text.

Here's an example:

The highlighting isn't distinct enough to catch my eye. I often resort to shrinking the terminal to only display a few lines, so I can find the highlighted text faster.

It'd be helpful for me if there this was more distinct or if it caught your eye faster. For example, when using Find in Safari, Find will briefly and quickly enlarge the selected text and highlight it yellow to catch your eye.
