prevent pandoc from inserting vertical bars in metadata block?

prevent pandoc from inserting vertical bars in metadata block?

[-- Attachment #1.1: Type: text/plain, Size: 1363 bytes --]

I'm using another application that outputs MultiMarkdown with a metadata 
block in the following format:

Title: Blah blah blah
Author: Doo de Doo
Base Header Level: 1
Bibliography: Pubs.bib
Lang: en-GB

Converting this using pandoc -f markdown_mmd -t markdown --standalone we 
get a metadata block in the following format:

---
author: |
  Doo de Doo
baseheaderlevel: |
  1
bibliography: |
  Pubs.bib
lang: |
  en-GB
title: |
  Blah blah blah
---

Is there any way within pandoc to get rid of the vertical bar and newline 
in the metadata fields so that each metadata field is on a single line like 
in the input file? I know I can pipe the file to something like perl (which 
has been my workaround) but was wondering if there is a way to do it only 
with pandoc? (The vertical bar, or whatever it corresponds to in pandoc's 
AST, causes trouble in epub output by inserting an unwanted p element 
within title and author elements in the title page.)

I just pushed a fix for this.

In the mean time you could work around this by using
a Lua filter that converts MetaBlocks elements to MetaInlines.

Wouldn't one then have to check that the MetaBlock element contains only a
Para or Plain element and unpack that element into the MetaInlines element?

I didn't go into the details, but yes, exactly.
