It's a (at least to me) known bug (I haven't taken the time to 
report it yet; found it a few days ago, when I reworked the 
docs). `formattedRead` treats space sometimes special and 
sometimes not, which (obviously) may lead to strange behavior, 
like it does here. If you like, you can [report this 
one](https://issues.dlang.org/enter_bug.cgi); I'll probably will 
care about it in a few weeks/months (I first want to fix the 
`formattedWrite` bugs and finish implementing formatting floating 
point numbers without calling `snprintf`.)

When using the `stable` docs you still should get, what you are 
used to. But I guess, you used the `master` docs and looked at 
`formattedWrite` where the information used to be.

Since about three weeks I'm on reworking completely the docs of 
`std.format`. Before that, the module has been split in several 
submodules (package, read, write, specs). Meanwhile I moved the 
docs you know from `formattedWrite` to 
[package](https://dlang.org/phobos-prerelease/std_format.html) 
(but yet not reworked completely, because the review process 
takes some time and I try to verify everything I state in the new 
docs in the source code). For 
[`formattedRead`](https://dlang.org/phobos-prerelease/std_format_read.html#.formattedRead) and [reading in general](https://dlang.org/phobos-prerelease/std_format_read.html), the new docs are already finished. Feedback is welcome.
