Error parsing tex with %\ after empty line inside of block

Error parsing tex with %\ after empty line inside of block

[Daurnimator]

Trying to compile:

\title{
Test

%\vspace*{20pt}
}

Results in:

pandoc:
Error at "source" (line 4, column 1):
unexpected '\n'
%\vspace*{20pt}
^

(I hope I reduced the test case down correctly)

Daurn.

It actually has nothing to do with the %. The problem is the blank line
inside \title{...}.

This sufficies to reproduce the problem:

```
\title{
Test

}
```

But note!  This won't compile with pdflatex either.  You can't have a blank line inside \title{}.
I don't think it's a bug if pandoc chokes on invalid latex.

xelatex seems to allow it.
I get the same error passing --latex-engine=xelatex

Some background: I wanted to see how pandoc compiled

xelatex chokes on my example with the same error as
pdflatex.

OK, here there is \\ before the blank line, preventing a
paragraph break.  This is where the problem really lies, I
think.

Why don't you submit an issue report with a link to the cqueues.tex
file and this thread?  That way we won't lose track of it.
