Avoid trimming whitespace from test cases?

[bjmc]

Thanks for this very useful library! I'm trying to test a grammar that requires files to be terminated with a newline, and I'm having trouble producing a passing test case with pest_test_gen. I wonder if the problem is that leading and trailing whitespace is being trimmed from the test case.

I can work around this by refactoring the pest grammar, but I wondered if there's any way to disable that feature?
