Avoid extraneous space between visibility kw and ident for statics

Today, given a static like `static mut FOO: usize = 1`, rustdoc would
emit `static mut  FOO: usize = 1`, as it emits both the mutability kw
with a space and reserves a space after the mutability kw. This patch
fixes that misformatting.

This patch also adds some tests for emit of other statics, as I could
not find an existing test devoted to statics.
