escape sequences for message syntax are throwing an error

[dagoltz]

File "/../my_file.py", line 103, in _process_message
return format(actual_message, processed_params, _get_message_format_locale(locale_code))
File "/.../lib/python2.7/site-packages/pyseeyou/init.py", line 13, in format
ast = ICUMessageFormat.parse(msg)
File "/.../lib/python2.7/site-packages/parsimonious/grammar.py", line 115, in parse
return self.default_rule.parse(text, pos=pos)
File "/.../lib/python2.7/site-packages/parsimonious/expressions.py", line 122, in parse
raise IncompleteParseError(text, node.end, self)
IncompleteParseError: Rule 'message_format_pattern' matched in its entirety, but it didn't consume all the text. The non-matching portion of the text begins with '{n,}: in regular ex' (line 1, column 14).

String example: "Disallowed: \\{n,\\}: in regular expression"

This should be supported as described here:

Supports escape sequences for message syntax chars, e.g.: "\{foo\}" will output: "{foo}" in the formatted output instead of interpreting it as a foo argument.

My workaround:
handle the string and inject those as parameters:

regex used: \\{([^{}]+)\\}

As with the previous problem, the PEG syntaxes have diverged significantly since pyseeyou took the PEG definition:

• https://github.com/messageformat/messageformat/commits/a12668e8f06ed7e290359a7781153315d3e03f17/parser.pegjs
• https://github.com/messageformat/messageformat/commits/master/packages/parser/parser.pegjs

It's going to take some time to re-sync it. I will take a try at it though.
