rst header with trailing space after name not recognized

[rpuntaie]

Pandoc 2.1.1

In this example

=====================
Software Requirements
=====================

------
Device
------

Requirements - Functionality
============================

Installer
---------

Driver 
------

About driver

converted to docx with

pandoc -f rst -t docx tmp.rest -o "tmp.docx"

I get

Driver ------

but not a

Driver

with header formating.

This is a rst reader problem because towards HTML

pandoc -f rst tmp.rest

I get the same:

<h1 id="software-requirements">Software Requirements</h1>
<h2 id="device">Device</h2>
<h3 id="requirements---functionality">Requirements - Functionality</h3>
<h4 id="installer">Installer</h4>
<p>Driver ------</p>
<p>About driver</p>

I can't reproduce (with pandoc 2.1.1 or 2.0.6)

$ cat tmp.rest      
=====================
Software Requirements
=====================

------
Device
------

Requirements - Functionality
============================

Installer
---------

Driver
------

About driver
$ pandoc -f rst tmp.rest
<h1 id="software-requirements">Software Requirements</h1>
<h2 id="device">Device</h2>
<h3 id="requirements---functionality">Requirements - Functionality</h3>
<h4 id="installer">Installer</h4>
<h4 id="driver">Driver</h4>
<p>About driver</p>

Maybe it has something to do with your line endings? What OS are you using?

[jkr]

Oh, I see -- it has to do with an extra space at the end of "Driver", i.e.
Driver \n------ instead of Driver\n------.

MWE:

$ echo 'Foo \n==='|pandoc -f rst
<p>Foo ===</p>

@jgm -- this is a bug, right? rst2html.py does it correctly.

[rpuntaie]

Yes, rst2html.py produces the title, even if there is a space after Driver.

[jgm]

Proper test case is

echo -e 'Foo \n==='|pandoc -f rst

and actually I DO get a header with this for pandoc 1.19.2.1, but not for 2.x.
So, apparently it's a regression? I tracked it down to f4bff5d where for some reason I replaced a blankline with newline.

Will fix immediately.
