Subject: edit() doubles backslashes when keep.source=TRUE
Is it just my installation or does edit() (or fix(), etc.) in R-4.0.0
double all the backslashes when options(keep.source=TRUE)? E.g.,
> options(keep.source=TRUE)
> f <- function(x) { cat("\t", x, "\n", sep="") }
> edit(f) # exit the editor without making any changes
The editor (vi or notepad) shows doubled backslashes
function(x) { cat("\\t", x, "\\n", sep="") }
as does the return value of edit().
If I set options(keep.source=FALSE) before defining 'f' or remove t's
'srcref' attribute then the backslashes are left alone.
