`utf8_encode(escapes = "31")` colors escapes and backslashes/quotes differently

[krlmlr]

This splits the output by opening/closing styling. In the first two examples, only the backslash is colored red. In the third example, \n is colored red.

@patperry: Is this intentional? Should we consistently color all characters in \" and \\ in red?

utf8::utf8_encode(c("\\", '"', "\n"), quote = TRUE, escapes = "31", display = TRUE) |>
  strsplit("\033[[][^m]*m")
#> [[1]]
#> [1] "\""   "\\"   "\\\""
#> 
#> [[2]]
#> [1] "\""   "\\"   "\"\""
#> 
#> [[3]]
#> [1] "\""  "\\n" "\""

This is intentional.

The feature is there to de-emphasize control and format characters in text, e.g.

corpus::as_corpus_text("Sam said \"it wasn't\na backslash (\\)\"")

That is, the goal is to make it easier to read text while simultaneously displaying the control/escape characters.
