 Q:

Why does curl allow use of the file URL scheme, but not wget

This question refers to curl 7.21.4 and GNU Wget 1.13.4, I don't know if the answer is version specific.
Using the file URI scheme I can get local file using curl as such
$ curl file://localhost/Users/dave/.vimrc
contents of.vimrc

However if I try the same using wget I receive an error:
$ wget file://localhost/Users/dave/.vimrc
file://localhost/Users/dave/.vimrc: Unsupported scheme `file'

Does anyone know why this is the case?

A:

Because Wget has not been written to support file:// URLs. (It's front web page clearly states "GNU Wget is a free software package for retrieving files using HTTP, HTTPS and FTP")
Allow me to point to a little curl vs wget comparison.

 Q:

Is there a way, using regular expressions, to match a pattern for text outside of quotes?

As stated in the title, is there a way, using regular expressions, to match a text pattern for text that appears outside of quotes. Ideally, given the following examples, I would want to be able to match the comma that is outside of
\int_0 ^ 1 \left (  \sum_{k=0}^\infty (-1)^k e^{-(k+1)x } x^{2012 } \right)\,dx   \\ 
 & = \sum_{k=0}^\infty \left (( -1)^k \int_0 ^ 1 e^{-(k+1)x } x^{2012}\, dx \right)   \\ 
 & = \sum_{k=0}^\infty \left (( -1)^k \int_0^{k+1 } e^{-t } \left(\frac{x}{k+1}\right)^{2012}\frac{1}{k+1}\, dt \right) \\ 
 & = \sum_{k=0}^\infty \frac{(-1)^k}{(k+1)^{2013}}\gamma(2013,k+1) 
 \end{align } 
 where $ \gamma$ is the lower incomplete Gamma function. Maple can't find a closed formula for this serial (and neither can I). It's even tricky to measure numerically, so I'm not sure how much practice it is.
