Latex: '#' in a backtick section isn't properly escaped

[jlargentaye]

In multimarkdown 6.2.3, the following input markdown:

I don't #define myself that way

`but what if I #define this?`

Generates the following Latex output:

I don't \#define myself that way

\texttt{but what if I #define this?}

Note that the the # (hash) sign from the first line is backslash-escaped in the output, but not the one in the backticked line. The latter causes a latex error: Illegal parameter number in definition of \reserved@a.

FWIW, MMD4 properly handled this case

Same for $ character in backticks
