#240 Recommended compand has syntax error

[Tom Epperly]

The documentation here:
http://sox.sourceforge.net/sox.html
suggests using
sox asz.wav asz-car.wav compand 0.3,1 6:−70,−60,−20 −5 −90 0.2
to reduce dynamic range for listening in a car.

When I try this command:
faerun:/tmp> sox 01_overture__prologue.mp3 over.mp3 compand 0.3,1 6:−70,−60,−20 −5 −90 0.2
sox FAIL compandt: syntax error trying to read transfer function value
faerun:/tmp>
I get the syntax error.

faerun:/tmp> sox --version
sox: SoX v14.4.1

This is on a Debian unstable system.

This is a ASCII vs. unicode issue: sox currently requires hyphens for minus-signs.

Possibilities: fix the HTML man page to use hyphens; use a unicode-aware sscanf.
