The docs of `std.format` are currently under strong revision, 
about 90% is already done, but that "feature" is among the other 
10%. I hope to get that ready till the end of the month, so the 
next stable release will have better docs.

Unfortunately it's much more difficult to change that strange 
behavior without breaking code. Currently I hope for Phobos 2.0 
coming soon and meanwhile try to prepare `std.format` for that 
change.
