Formatting for numbers with commas fails

[tomhundt]

Hi, this is an awesome package, thanks so much for providing it!

Noticed in one of my files, dollar numeric fields, e.g., [...,] "$100,015.00", [...] don't render properly -- the "string" rendering stops at the comma in the middle, whereupon it changes to the same style as numeric constants and dates. Experimentation reveals that the dollar sign makes it think that's a string-format field (any letter does the same thing). IMO the whole thing should just be displayed as a string, including the embedded comma.

Here's an example
one,two,three,four
1,"$200,000",567,hello
comes out as

Thanks
