2.18.1: Fix binary name for "cargo install"

It should always have been "riff" and nothing else.

2.18.0

Highlight "Binary files differ" lines

2.17.0: Improve headers highlighting

With this release, I made a conscious effort to add sensible
highlighting to diff and hunk headers.

2.16.3: Allow redirection comparisons

With this release, you can now do redirection comparisons in shells that
support them (#29):

$ riff <(echo hej) <(echo nej)

2.16.2: Dev-only changes

* #25 Fix running tests with a target triple
* #26 Bump Cargo.toml version when releasing

2.16: Implement --no-pager command line switch

This release also fixes a crash.

2.15: Improve highlighting heuristics

With this change in place, if more than 70% of a line is highlighted,
just show it without highlighting.

This replaces a more complex heuristic from before.

2.14: Handle invalid UTF-8 input

Previous releases would crash on invalid UTF-8 input.

To not crash, this release uses the following function for parsing
incoming data into strings:

2.13: Simpler highlighting

This release will highlight somewhat differently from before.

The new heuristic is:
1. Just diff the before and after versions
2. Remove any full-line or multi-line highlights

This simplifies some code and fixes some cases which were not
highlighted before. It probably breaks some things as well, do provide
examples at <https://github.com/walles/riff/issues/23>!

Additionally this release documents how to get "git log -p" output
highlighted.

2.12: Performance release

Riff was actually pretty fast even before this release, this is more of a
because-I-could release.

This release is about 60% faster than the previous one.

Or, about 12x slower than plain cat.
