Subject: [PATCH] Reformat with context: do not touch blocks with read only
 spacing property.

Spacing is set to read-only by FormattingModelBuilder implementors, so they expect spacing to be really read-only, however if WhiteSpace is read-only but Spacing is not, it means that we are formatting text range, and current WhiteSpace is not located inside, so we can modify in such a case
