Assert the entire lines using Equals instead of Contains. This makes the tests a
bit easier to read, and it makes it much easier to decide how they need to be
changed when we change the layout (like we do in the last commit of this
branch).
It is true that this requires changing all these tests for any future UI
changes, but I think this is a good price to pay; those adaptions are trivial
and can be done without thinking.
In most real-world scenarios, name and path are usually the same. They don't
have to be though, and it's important to make sure we use the right one when
passing arguments to git commands, so change the tests to have different name
and path.
By constructing an arg vector manually, we no longer need to quote arguments
Mandate that args must be passed when building a command
Now you need to provide an args array when building a command.
There are a handful of places where we need to deal with a string,
such as with user-defined custom commands, and for those we now require
that at the callsite they use str.ToArgv to do that. I don't want
to provide a method out of the box for it because I want to discourage its
use.
For some reason we were invoking a command through a shell when amending a
commit, and I don't believe we needed to do that as there was nothing user-
supplied about the command. So I've switched to using a regular command out-
side the shell there
