strutil: accept leading whitespace in parse rational 

Programmatic output of floating point numbers might choose to print
spaces instead of an explicit '+' sign, to align the output with the
result of formatting negative numbers yet achieve a screen appearance
similar to what humans would have written. Skip leading whitespace
before insisting in seeing either signs or digits or decimals.
