colnames argument does not appear to work

[jwhendy]

Greetings,

I'm using v2.2 here (not CRAN due to issue #17 ) and just noticed that colnames does not appear to be taking. A test:

> dat <- data.frame(id = letters[1:3], val = 1:3)
> dat
  id val
1  a   1
2  b   2
3  c   3

> ascii(dat)
|==================== 
1.1+| h| id h| val  
| 1 | a  | 1.00 
| 2 | b  | 2.00 
| 3 | c  | 3.00 
|==================== 

> ascii(dat, colnames = c("col1", "col2"))
|==================== 
1.1+| h| id h| val  
| 1 | a  | 1.00 
| 2 | b  | 2.00 
| 3 | c  | 3.00 
|==================== 

I believe I supplied this correctly based on the docs:

colnames
Character vector (replicated or truncated as necessary) indicating colnames of the corresponding columns. If NULL (default) the column names are not modified

Is this on my end or a legitimate issue?
