Multiline strings break line numbers

[sarranz]

This program

#annot="
very
long
annotation
string
"
export fn main(stack u8[1] a) {}

reports

"ble.jazz", line 2 (27-28):
typing error: a has kind stack, only reg or reg ptr are allowed in parameter of non inlined function

but the error is not in line 2. I guess it's difficult to distinguish between this and annot="very\nlong\nannotation\nstring?

Fixed in #959.
