Hi,

I noticed the PEG parser does not support the full PEG grammar, this 
includes comments, double quotes, escaping and underscores.

The attached patch adds support for those (I sent it to guile-devel but 
I guess it's better to do it here).

I'm trying to test it with Zig's grammar but I'm having some issues and 
the way this is generated it's really hard to test. As is, this patch 
passes all the current tests in Guile which includes being able to parse 
peg-as-peg, which now has comments and features that were not 
implemented before.

Thank you,
Ekaitz

Egun on!

Finally pushed v4 with slight edits to ‘NEWS’:

  ff11753df PEG: Add full support for PEG + some extensions

Thank you!
