[PATCH RESEND] parser: handle negative numbers properly

Yeah, but you're breaking the parsing of sync intervals which use NUMBER
DASH NUMBER. You can fix this in two ways -- use your current hack to
glue the '-' to the following number and then go fix the sync interval
parsing to handle negative numbers, or fix the places where a negative
number is valid to handle DASH NUMBER as well as just NUMBER.

Can you briefly enumerate where negative numbers are valid in the config file?

Nice fix there.
