Highlight searched string in commit view [Enhancement]

[benzht]

I really love the ease of searching for the occurrence of "string" in commit-diff's en commit messages to find relevant commits.

But when subsequently switching to the commit view, on larger commits it can be very tedious to find the string back.

It would be great if the commit view would feature either

1. automatically highlighting the searched-for string in the commits,
2. would feature a 'regular' Find... dialog searching for arbitrary strings
