Michael J Gruber 7b88176e9b pretty: Introduce ' ' modifier to add space if non-empty ...

We have the '+' modifiier which helps combine format specifiers which
may possibly be empty, e.g. '%s%+b%n'.

Introduce an analogous ' ' (space) modifier which adds a space before
non-empty items. This helps assemble "one line type" format specifiers.
