Incorrectly renders inline code containing an underscore

[joshdoman]

Inline code that contains an underscore is misinterpreted as italics if there exists an underscore later on the same line. This is particularly problematic if you have code with two underscores or code followed by italics.

Example:

Expected:
OP_CAT and hello
OP_CAT_HELLO
