- Extends URLSearchParams API to include operations for combining
different URLSearchParams objects:
These new methods include:
setAll(otherParams): performs `this.set(key, values[0])` for each
key/value-list pair in `otherParams`
appendAll(otherParams): performs `this.append(key, values)` for
each key/value-list pair in `otherParams`
replaceAll(otherParams): for each key/value-list pair in
`otherParams`, replaces current set of values for `key` with
a copy of the list of values.
- RequestOptions do not merge search params automatically (because
there are multiple ways to do this). Instead, they replace any
existing `search` field if `search` is provided. Explicit merging
is required if merging is desirable.
- Some extra test coverage added.
