Go テンプレート式内の過剰な空白の trim を報告します。
Inspection follows the following logic applied to each statement:
1. Doesn't have any trims → Skip it
2. Has both trims and is surrounded by non-blank elements → Problem
3. Has both trims and has preceding or succeeding non-blank elements → Problem if it produces values (e.g., it is a non-empty element
itself)
4. Has the left trim and preceding non-blank element → Same as the previous one
5. Has the right trim and succeeding non-blank element → Same as the previous one
