Should reprex output add new lines with long (wide) error & warning messages?

[EconomiCurtis]

When a reprex output shows a long warning or error message, it does not add new lines consistent with typical experience with character max-widths from the R console.

For example, (perhaps an odd example, but it's one I recently used on RStudio Community)

library(dplyr)
df <- tibble(
  y = LETTERS[1:3],
  x1 = 1:3,
  x2 = 3:5
)
lm(y ~ x1 + x2, data = df)

this produces a somewhat long error,

#> Warning in storage.mode(v) <- "double": NAs introduced by coercion
#> Error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...): NA/NaN/Inf in 'y'

In the console, this appears as the following,

On Stack Overflow, this appears as the following (not you have to scroll left to see the full error)

That horizontal scrolling can be awkward for some folks. Particularly for long errors and warnings (e.g. some package install errors). I feel it'd be ideal for warning and error messages to roughly replicate the new lines seen in the R console.

New lines can certainly be added manually -- I have a feeling there are other concerns or trickiness I'm missing -- but I feel the default behavior should be with styling that works better on gh, so, and rstudio community.

yihui/knitr#1142 has advice on "customize the error/warning hook function to wrap the error/warning message"

A hack Hadley has used in book-y projects to wrap errors and warnings: https://github.com/hadley/adv-r/blob/dc49c3872c3530ac08716fd4f4c235b01266a4ce/common.R#L44-L64

@cderv Do you have any quick input? As in, is there some simple knitr option I could use to wrap errors and warnings? I suspect not.
