1. Fix cargo publish error due to examples without path …

   Without this, we get a strange error:
   
   ```
   % cargo publish --dry-run
       Updating crates.io index
      Packaging textwrap v0.15.0 (/home/mg/src/textwrap)
      Verifying textwrap v0.15.0 (/home/mg/src/textwrap)
   error: failed to verify package tarball
   
   Caused by:
     failed to parse manifest at `/home/mg/src/textwrap/target/package/textwrap-0.15.0/Cargo.toml`
   
   Caused by:
     can't find `hyphenation` example at `examples/hyphenation.rs` or
     `examples/hyphenation/main.rs`. Please specify example.path if you
     want to use a non-default path.
   ```
   
   This happens even though the file is there:
   
   ```
   % ls examples/hyphenation.rs
   examples/hyphenation.rs
   ```
   
   Specifying an explicit path helps and should let the release go
   through.
