looks like current {lintr} dev fails on the code now. @MichaelChirico are you aware of that lintr change and is it intentional?

File `R/roxygen-examples-parse.R` is not lint free
Warning: file=/home/runner/work/styler/styler/R/roxygen-examples-parse.R,line=146,col=13,[function_left_parentheses_linter] Left parenthesis should be on the same line as the function's symbol.
Error: File R/roxygen-examples-parse.R is not lint free

Offending expression:
