David Majda a56d3ac94f Fix error messages in certain cases with trailing input 
In case the generated parser parsed successfully part of input and left
some input unparsed (trailing input), the error message produced was
sometimes wrong. The code worked correctly only if there were no match
failures in the successfully parsed part (highly unlikely).

This commit fixes things by explicitly triggering a match failure with the
following expectation at the end of the successfully parsed part of the
input:

  peg$fail({ type: "end", description: "end of input" });

This change also made it possible to simplify the |buildMessage|
function, which can now ignore the case of no expectations.

Fixes #119.

PEG.js Spec Suite
=================

This is the PEG.js spec suite. It ensures PEG.js works correctly. All specs
should always pass on all supported platforms.

Running in a browser
--------------------

  1. Make sure you have Node.js and all the development dependencies specified
     in package.json installed.

  2. Run the following command in the PEG.js root directory (one level up from
     this one):

       make browser

  3. Start a web server and make it serve the PEG.js root directory.

  4. Point your browser to an URL corresponding to the index.html file.

  5. Watch the specs pass (or fail).

If you have Python installed, you can fulfill steps 3 and 4 by running the
following command in the PEG.js root directory

  python -m SimpleHTTPServer

and loading http://localhost:8000/spec/index.html in your browser.

Running from a command-line
---------------------------

  1. Make sure you have Node.js and all the development dependencies specified
     in package.json installed.

  2. Run the following command in the PEG.js root directory (one level up from
     this one):

       make spec

  3. Watch the specs pass (or fail).
