Some editors with +"smart" indentation will insert whitespace at the beginning of new lines as +appropriate, so you can start typing the next line of code right away. +However, some such editors do not remove the whitespace if you end up not +putting a line of code there, such as if you leave a blank line. As a result, +you end up with lines containing trailing whitespace. + +Git will warn you about patches that introduce trailing whitespace, and can +optionally strip the trailing whitespace for you; however, if applying a series +of patches, this may make later patches in the series fail by changing their +context lines. + Chapter 4: Naming -- 1.5.2.1 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
