We're not trying to be accurate in terms of finding errors; if you provide invalid code, there's no way for us to flag it. The goal of Pygments is to highlight semantically correct code.

[verhovsky]

Pygments is highlighting the backslashes as errors but they're not errors. It is correct code, it comes from here

# backslash suppresses the special meaning of characters:
set amount \$16.42


# backslash adds special meaning to certain characters:
puts lots\nof\n\n\n\n\n\nnewlines
