backslash-escaped leading space in markdown table treated as a literal backslash

backslash-escaped leading space in markdown table treated as a literal backslash

I think this is a relatively recent regression. `\ ` at the start of a line 
normally gets treated as a space:

> pandoc
one

\ two

three
<p>one</p>
<p> two</p>
<p>three</p>

But if it's in a table, it gets preserved now. HTML below:

> pandoc
one | one
----|---
two | two
\   | three
<table>
<thead>
<tr class="header">
<th>one</th>
<th>one</th>
</tr>
</thead>
<tbody>
<tr class="odd">
<td>two</td>
<td>two</td>
</tr>
<tr class="even">
<td>\</td>
<td>three</td>
</tr>
</tbody>
</table>

Native output looks like this:

[Table [] [AlignDefault,AlignDefault] [0.0,0.0]
 [[Plain [Str "one"]]
 ,[Plain [Str "one"]]]
 [[[Plain [Str "two"]]
  ,[Plain [Str "two"]]]
 ,[[Plain [Str "\\"]]
  ,[Plain [Str "three"]]]]]

Versus this for the non-table version:

[Para [Str "one"]
,Para [Str "\160two"]
,Para [Str "three"]]


This has only started recently. I noticed it today in a document I last 
processed in October 2017.

This is because we strip trailing spaces before parsing the
cell (that's not a new change).  Note that if you have
`\ a` in your cell, the escaped space will work; it's only
at the end that it doesn't, and this mirrors how a paragraph
ending in a `\` with no following space is treated.

Are there real-world examples where you need the `\ ` in a
cell with nothing else?

I've been using it to generate html tables where the first cell in a row is 
empty. I can substitute   of course, but using a \ seemed superior to 
using html.

Further thoughts? Should I just use the html in my markdown, or is there a 
markdown-y way to do it? I would have thought an empty leading cell was not 
uncommon.
