Bold/italics not converted properly when starting or ending with space

[ripperdoc]

Pandoc 2.11.2

I found that the bold and italics tags in Mediawiki are not recognized if the text they envelop start or end with whitespace.

So:

pandoc -f mediawiki -t html <<< "'''Should be bold '''"
<p>'''Should be bold '''</p>

pandoc -f mediawiki -t html <<< "''' Should be bold'''"
<p><em>' Should be bold</em>'</p>

pandoc -f mediawiki -t html <<< "'''Should be bold'''"
<p><strong>Should be bold</strong></p>

I've seen this quite often in Mediawikis in the wild.

We have a check for a nonspace in the code. I'm not sure why it's there, but very possibly someone used a parser for another format as a base in constructing this. We could take it out, if you can confirm that mediawiki doesn't care about the space after the opening delimiter.

At least if I try in their test editor here (using the Source mode, not Visual), it correctly formats the word regardless of leading or trailing space.
