Time-Piece: Use isSPACE, not isspace

The latter gives results that are dependent on the program's underlying
locale, and so may be inconsistent.

If locale dependence is actually desired, isSPACE_LC should be used, as
it knows about various things the module writer shouldn't have to
concern themselves with.  It is supported since 5.004
