No line break when dollar sign follows minus

Spec: http://unicode.org/reports/tr14/#PR.
"Many currency signs can appear on both sides, or even the middle, of a numeric expression.
Therefore the line breaking algorithm, by default, does not break between PR and numbers or
letters on either side."
Here PR refers to:
002B    PLUS SIGN
005C    REVERSE SOLIDUS
00B1    PLUS-MINUS
2116    NUMERO SIGN
2212    MINUS SIGN
2213    MINUS-OR-PLUS-SIGN
