Jarrod Johnson b606882327 Have collate preserve relative whitespace
The change to tolerate either a space or no space ended up
greedily consuming whitespace.  Do best possible in two cases:

For log, use the first line as a clue, and consistently pad or not pad
according to first line.  It won't catch different pad strategies, or
handle first line being indented but other lines not being indented.

For the textgroup variant, allow subsequent lines to revise the
pad downward, and accept any whitespace, not just space.
