rmarkdown::render() corrupts input file #2534
Description
Issue:
Made a typo and instead of rmarkdown::render("report.rmd") wrote rmarkdown::render("report.rds"). To my surprise, rmarkdown finished without error, but the rds file was mangled. This shouldn't happen.
Why this is an issue:
Somewhere in the pipeline, the input file is being modified. This means that potentially, the call of rmarkdown::render(input) can corrupt the input file. This breaks the assumption of the call being safe.
MRE:
saveRDS("test", "test.rds")
rmarkdown::render("test.rds") # no error
readRDS("test.rds") # errorReproduced on both the latest cran and the development version of rmarkdown.
