mel-computations cli help text "=" missing

[boeddeker]

The help text of compute-mfcc-feats says that the --high-freq < 0 is the offset from Nyquist.
But the code says it is --high-freq <= 0.
In my mind should the help text say --high-freq <= 0 is the offset from Nyquist.

Here the code positions:

kaldi/src/feat/mel-computations.h

Line 66 in 8ce3a95

"High cutoff frequency for mel bins (if < 0, offset from Nyquist)");

kaldi/src/feat/mel-computations.cc

Line 46 in 8ce3a95

if (opts.high_freq > 0.0)

OK, you can make a PR if you have time.
