data missing - no `fill = TRUE` option

[data-al]

When using read_csv_chunkwise if there is data missing in the first line of file (or second line, as the case may be header = TRUE) there is no option to use fill=TRUE and the following error is shown:

Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec, : line 1 did not have 13 elements

can this be solved somehow ?
