Implicit vs explicit printing of problems

[jennybc]

We're reading an (intentionally) tricky file in via readr. We hadn't planned on anyone using read_table() or read_table2() and yet ... someone did. Their expectation that these functions would work supports the viewpoint in #717 (make read_table() behave like read.table()).

Anyway, there are many problems, which makes sense. But the printing of the problems during import vs. explicit print after the fact suggests there's a printing problem.

I'm getting (i think) the same printing problem parsing failure warning even with read_fwf:

Warning: 1 parsing failure.
row # A tibble: 1 x 5 col       row   col               expected actual        file expected     <int> <chr>                  <chr>  <chr>       <chr> actual 1 1047945   X12 no trailing characters   1 99 'pawg.data' file # A tibble: 1 x 5

The printing issues look to be fixed in the devel version
