With this release, you can now search backwards with '?', just like in
less.
The new show-help mapping is 'h' (also like in less). Unfortunately this
conflicts with the old 'h' mapping (from vim), but since less
compatibility is what's important here the vim binding had to go.
This release also improves styling. Some bugs have been fixed, and the
UI now matches the plain text style. In some circumstances, making the
window narrower now doesn't cause the text to wrap and scroll, which is
nice.
