Clean up help text some more, so that it doesn't imply in parts that negative

quality levels aren't permitted.

 files for streaming.
 .IP "-q n, --quality=n"
-Sets encoding quality to n, between -1 (low) and 10 (high). This is the default mode of operation, with a default quality level of 3. Fractional quality levels such as 2.5 are permitted. Normal quality range is 0 - 10.
+Sets encoding quality to n, between -1 (very low) and 10 (very high). This is the default mode of operation, with a default quality level of 3. Fractional quality levels such as 2.5 are permitted. Using this option allows the encoder to select an appropriate bitrate based on your desired quality level.
 .IP "--resample n"
 Resample input to the given sample rate (in Hz) before encoding. Primarily
 useful for downsampling for lower-bitrate encoding.
