Description
By default, for email formatted patches, ParsePatchHeader will remove all content in square brackets and place it in a separate field. This matches the default behavior of git, but git also includes flags to disable cleaning completely or to only remove content in square brackets that contains the word PATCH.
It should be a backwards-compatible change to have ParsePatchHeader accept option functions that can disable the default behavior or switch to only removing [PATCH] content.
