Markdown Discuss - Aug 2017 - whitespace at the start of code in a blockquote trimmed

Hi,

In a document I'm writing I wanted to include an extract from an email
message as a blockquote.
The message contains a code extract which contains both a piece of ascii
art (output from banner) as well as some lines that start with spaces.

After converting the markdown to XHTML I noticed that the ascii art does
not look as expected and some lines that start with spaces are displayed
left-aligned. (Meaning the leading spaces are removed).

The problem occurs only when the blocquote (> ) and code (4spaces) are
combined.
Adding two more spaces somehow resolves the problem as well but that
obviously makes the Markdown text look different.

I've created a small sample and uploaded it to pastebin at
https://pastebin.com/iCb3ESYZ.
It has the original text, the same text without blockquote and the version
with the additional spaces added.
Converting that in dingus (
https://daringfireball.net/projects/markdown/dingus) demonstrates the
problem.

Is this by design?
Is there another way to avoid this?

Thanks in advance

Bram

Looks like a bug in Markdown.pl. Pretty much all the other implementations of
Markdown handle this correctly. So you can use another Markdown parser, or
alternatively you can write the whole blockquote in HTML as a workaround. I
think you can add spaces to all the lines too (so it looks better in the text
document). Or you take some time to fix Markdown.pl.
