Jeffrey Finkelstein 294bde8e08 seq: correct width for certain negative decimals
Fix a bug in which a negative decimal input would not be displayed with
the correct width in the output. Before this commit, the output was
incorrectly

    $ seq -w -.1 .1 .11
    -0.1
    0.0
    0.1

After this commit, the output is correctly

    $ seq -w -.1 .1 .11
    -0.1
    00.0
    00.1

The code was failing to take into account that the input decimal "-.1"
needs to be displayed with a leading zero, like "-0.1".
