Closed
Description
Description
BasicFormat should not add a mandatory leading space if one already exists on the previous trailing or there is no previous. Similarly it should not add a trailing space if one already exists on the next leading or there is no next.
A good example of this is when combining refactorings. Placeholder expansion may want to format the returned closure. But if that closure is then used by a trailing closure conversion, we'll end up with two spaces between the arg label and the closure.
Steps to Reproduce
Format a simple closure ({ <#code#> }). That produces -
{
<#code#>
}
Then if that is added in a call as an additional trailing closure and that call is formatted we end up with two spaces, since we also add a space after : -
call {
<#code#>
}arg2: {
<#code#>
}
