Multiple chunk dependency not working with c() syntax

[cmmp]

A multiple chunk dependency defined with c() does not compile. It works with 'a;b' syntax though.

c() syntax is defined in the manual http://cloud.github.com/downloads/yihui/knitr/knitr-manual.pdf along with 'a;b'

sample file:

\documentclass[a4paper]{article}

\begin{document}

\title{Test}

\maketitle

<<a>>=
x = 1
@ 

<<b>>=
y = 2
@ 

\section{Test}

<<c, dependson=c('a','b')>>=
z = x + y
@ 

\end{document}

output error:

Error in for (i in sc_split(deps)) dep_list$set(structure(list(c(dep_list$get(i),  : 
  invalid for() loop sequence
Calls: knit ... process_file -> split_file -> lapply -> FUN -> parse_block

Thanks for the report. I actually do not like the old a;b syntax and c('a', 'b') makes me feel much better.
