pub fn merge(
cli: Overrides,
file: Config,
default_author: String,
) -> Result<Resolved>Expand description
Fold the command line over the file.
Lives here rather than inside main so that it can be tested at all: the precedence is
three ors and an extend, any one of which could be turned around without a single test
noticing, and the result decides which host a URL reaches.
The command line wins, because it is what was typed for this run. Aliases are the exception and are added rather than replacing: naming one host on the command line should not silently drop the six in the file.
