[iterator.operations, range.iter.op.distance] Reword "get to".
It was previously not explicitly stated that input iterators would
actually be incremented (which invalidates copies). The new wording is
more explicit about how the distance is measured, and in doing so
calls out more explicitly that input iterators are indeed incremented.

[range.nonprop.cache] Clarify emplace-deref for prvalues. (#4732)
A new note explains that `emplace-deref` requires implementations to
avoid materialization of the result of `*i` before the initialization.
This is implied by the normatively expressed requirement in terms of
an invented initialization of a variable, but is easily overlooked.

[meta.member] Clarify is_corresponding_member semantics
The definition of 'common initial sequence' in [class.mem] only applies
to standard-layout struct types, which excludes unions. There is no
reason to define is_corresponding_member in terms of standard-layout
types (which includes unions and scalars and arrays of such types) when
the common initial sequence is only meaningful for standard-layout
structs.

"The placeholder type" gives the wrong impression that we're talking
about the case from the previous paragraph. We're not; this is parallel
to the previous paragraph so should use parallel wording.

[fstream.syn] Fix grammar
"are only be provided" is not a valid english verb phrase. I'm not sure if
the intent was "are only provided" or "are only to be provided", but I think
the first more closely adheres to our style of making existential statements
about library implementations.
