Tabs in code blocks should not be replaced with spaces

Concerns the Markdown to HTML test for fixture markdown_documentation_syntax.md

Source:

Markdown provides backslash escapes for the following characters:

    \   backslash
    `   backtick
    *   asterisk
    _   underscore
    {}  curly braces
    []  square brackets
    ()  parentheses
    #   hash mark
    +   plus sign
    -   minus sign (hyphen)
    .   dot
    !   exclamation mark

Corresponding HTML file:

<pre><code>\   backslash
`   backtick
*   asterisk
_   underscore
{}  curly braces
[]  square brackets
()  parentheses
#   hash mark
+   plus sign
-   minus sign (hyphen)
.   dot
!   exclamation mark
</code></pre>

The tab \t between + and plus are expected to be replaced with spaces. We should look at other parsers' behaviors, and probably modifiy the test to expect the tabs to be left untouched.

👍

A use case for this is when documenting Makefiles, since the difference between a tab and a space means the difference between a working and non-working Makefile.

Ironically, it seems that GitHub's parser is replacing your tabs with spaces in the above example, so I was having a hard time following the description at first. 😆

For anyone else trying to find a workaround for this in GitBooks, this works:

<pre><code class="lang-sh">
foo:
&Tab;echo "bar"
</code></pre>
