The leading \ in an escaped dollar sign is displayed when \$ is used in a code block.

I commonly use $ in bash code blocks to denote the prompt in an interactive session. Something like:

$ rm -rf /

Github displays this just fine, but IPython needs $ to delimit inline LaTeX math expressions (c.f. #3427 and #3428).

In most places, IPython does the right thing and only displays $ when a user enters \$. However, in a code block, IPython will display something like:

\$ grep foo

When I really want it to look like:

$ grep foo

even though I actually entered \$ in the input to the markdown cell. Like this:

I need to escape the $ in the code block since MathJax interprets it as the beginning of an inline math sequence, even though it's part of a code block.

Shoot, I just tried again in master and it looks like this has been fixed. The solution is to not escape the $.

It seems it was not fixed for all languages. For bash it's ok but Javascript code blocks still cannot escape the $ sign.
