46ab14437e Don't flatten a block containing a single macro call 
We no longer flatten a block that looks like this:

```rust
match val {
    pat => { macro_call!() }
}
```

Currently, rust ignores trailing semicolons in macro expansion in
expression position (see https://github.com/rust-lang/rust/issues/33953)

If this is changed, flattening a block with a macro call may break the
user's code - the trailing semicolon will no longer parse if the macro
call occurs immediately on the right-hand side of the match arm
(e.g. `pat => macro_call!()`)

1d4b988414 Strip leading | in match arm patterns 
This addresses issue #2621

This commit turns out to be a partial revert of
ea3c01e337

The rationale is that a `|` character preceding a match pattern is not
semantically relevant and therefore should be considered a
style/formatting choice.

A discussion concluded that the best way to emit consistent formatting
here was to strip the leading `|`

This removes the match_with_beginning_vert test because it was asserting
the old behaviour which has been changed, it adds a new test
(issue_2621) which should be a more comprehensive check of the behavior
of `|` in match arms.
