Details:
Wave files are word-aligned, yet the last extra align byte that could appear
in an 8-bit sample width single channel wave file (i.e., a file with block
align equals to 1) shoudn't appear as an extra -1 value (unsigned char zero
mapped to a [-1;1) range) in the wavread resulting vector.
I've made two 7-samples 8bit wave files that reproduce this issue. The vector
size when reading them from octave is 8.

8.wav has RIFF size counting the last align byte, 8_sizeok.wav has RIFF size
not counting that extra byte
