Make rustfmt work & run it

Although it occurs in other places, including a path in rustfmt.toml
doesn't work:

$ rustfmt  src/*.rs
Could not parse TOML: expected a table key, found a period at line 1 column 1

So instead I just pasted the content of the referenced file. Now
rustfmt does work, and makes some minor stylistic changes, included
here.

Test: rustfmt src/*.rs
