.val appears to be printing strange

[njtierney]

When using .val I get some strange printing, which doesn't happen if I use another inline markup like .key.

Here's a reprex:

library(cli)
n_dist <- 4
dim <- c(5,1)
weights_dim <- c(2,5,1)
msg <- cli::format_error(
  c(
    "the dimension of weights must be either:",
    "{.val {n_dist}x1} or \\
    {.val {n_dist}x{paste(dim, collapse = 'x')}}",
    " but was {.val {paste(weights_dim, collapse = 'x')}}"
  )
)

stop(msg, call. = FALSE)
#> Error: the dimension of weights must be either:
#> "4x1" or "4x\"5x1\""
#> but was "2x5x1"

library(cli)
msg <- cli::format_error(
  c(
    "the dimension of weights must be either:",
    "{.key {n_dist}x1} or \\
    {.key {n_dist}x{paste(dim, collapse = 'x')}}",
    " but was {.key {paste(weights_dim, collapse = 'x')}}"
  )
)

stop(msg, call. = FALSE)
#> Error: the dimension of weights must be either:
#> [4x1] or [4x5x1]
#> but was [2x5x1]

Also worth noting when I do this in Rstudio, I get:

> stop(msg, call. = FALSE)
Error: the dimension of weights must be either:
"\033[34m4\033[39mx1" or "\033[34m4\033[39mx\033[34m\"5x1\"\033[39m"
but was "2x5x1"

Simpler reprex:

❯ cli::cli_text("pre {.val x {'foo'} y} post")
pre "x \033[34mfoo\033[39m y" post
