We need tests to cover this.

I don't think it's valid to have partial whitespace on the line, that's weird. Also I don't think we should remove whitespace if they include it (the whitespace may be important to the user, it should be preserved).

So what you're saying is no need to account for the fact where the blank line is not really empty but contains whitespaces? Also, I thought I am not removing any whitespaces as I am only checking for the output of the TrimSpace function but not assigning it to anything.

I think a heredoc indented with 2 tabs, having an "empty" line with only 1 tab, is not valid.

I also think a heredoc with 2 tabs, having an "empty" line with 3 tabs is valid, and it should preserve that 1 tab as real text (after stripping the leading 2 tabs)

@francislavoie I think it should now cover the cases you mentioned. I also added test cases but please let me know if we need more. Thanks.

All the feedback items above should now be resolved. Thank you for your prompt feedback @francislavoie!

Hmm, the CLA bot is down, I think. I guess we'll have to wait for it to wake up 😂 but that's fine
