[PATCH] minstat: default width is terminal width, not 74

The man page states that:
'-w width    Width of ASCII-art plot in characters, default is 74.'

This is not entirely correct. The mini-help is more accurate:
'-w : width of graph/test output (default 74 or terminal width)'

In other words: the man page fails to explain that ministat will default
to the terminal width, not 74. It will only fall back to 74 if 'COLUMNS'
is not set and ioctl(TIOCGWINSZ) fails.
