What type should the value column have?

tibble::enframe(character())
#> # A tibble: 0 x 2
#> # ... with 2 variables: name <int>, value <chr>

- `enframe(NULL)` now returns the same as `enframe(logical())` (#352).
- `tbl[1, , drop = TRUE]` now behaves identically to data frames (#367).
- The `tibble.width` option is honored again (#369).
- Faster printing of very wide tibbles (#360).
- Update vignette to match changes in 1.4.1 (#368, @bgreenwell).
- Don't rely on `ncol()` for `glimpse()`, only query `nrow()` and `head()`.
- Return input for zero-column data frames.
- Add test for `glimpse()` with unknown rows (#366, @kevinykuo).
- Faster construction and subsetting for tibbles (#353).
- `tribble()` now ignores trailing commas (#342, @LaDilettante).
- Fix error message when accessing columns using a logical index vector (#337, @mundl).
