Hard to parse inline parsing error

[hadley]

It's hard for me to understand this error (which I think is new in https://github.com/yihui/knitr/commit/3cbf47f31efebc28b59ac35c2ba07cbd3dd844ac)

knitr::knit(text = "`r 1 + `", quiet = TRUE)
#> Quitting from lines 1-1 (cilia-stag_reprex.spin.Rmd)
#> Error: Failed to parse the inline R code: 1 +  (Reason: <text>:2:0: unexpected end of input
#> 1: 1 + 
#>    ^)

^{Created on 2022-09-20 with reprex v2.0.2}

I'd find it easier to understand if it was more like:

#> Error: Failed to parse the inline R code: `1 + `
#> Reason: <text>:2:0: unexpected end of input
#> 1: 1 + 
#>    ^

Thanks! The error message includes `r ` now, and the reason is written to the next line:

#> Error: Failed to parse the inline R code: `r 1 + `
#> Reason: <text>:2:0: unexpected end of input
#> 1: 1 + 
#>    ^

Much better, thanks!
