files examples in specification reference have extra spaces

[demurgos]

I was reading the examples for the files field in the specification reference and was confused by the extra spaces:

guides/specification-reference.md

Lines 136 to 146 in 751b95c

	<pre class="ruby"><span class="ruby-identifier">require</span> <span class="ruby-string">&#39;rake&#39;</span>

Rendered:

require 'rake' 
 spec.files = FileList['lib     .rb', 
                       'bin/*', 
                       '[A-Z]*', 
                       'test/   *'].to_a 
  
 # or without Rake... 
 spec.files = Dir['lib/   *.rb'] + Dir['bin/*'] 
 spec.files += Dir['[A-Z]*'] + Dir['test/**/*'] 
 spec.files.reject! { |fn| fn.include? "CVS" } 
 

These spaces were already present before and removed in 19948c7, but introduced back again in 2ca58b0.

The spaces are an issue themselves, but the fact that this issue was already fixed in the past and then regressed due to a rebuild suggests that it should be fixed somewhere else too in order to fix it once and for all.

This has been fixed by 9276fa2, which I committed accidentally to the gh-pages branch without going through a PR (oops 😳).

I did check that rebuilding the file does not undo the fix, so it should be fine now 👍.

Thanks for reporting this!
