More explicit build instructions

@ssomers does this help, or do you think there is more we should say?

2e82a8dc9e Auto merge of #1304 - RalfJung:backtrace-sep, r=RalfJung
add empty line before backtrace, to separate it from help text

I think this improves how things look, and makes it easier to see the help text (it currently kind of drowns next to the backtrace).

Before:

ae2a811eee Auto merge of #1305 - ssomers:map_first_last_vs_miri, r=RalfJung
Replace last_entry with last_key_value

Wondering why `last_entry` was introduced (in #1156) while the alternative is shorter and seems clearer to me.

Also, as the perpetrator of map_first_last, I now think that `first_entry`/`last_entry` are silly methods because they're supposed to be constant time (as opposed to `entry`), so there's no money to be made by doing multiple things with the entry.
