" About working with automatic indenting:
"   -Any time you act on a line in an edit session with automatic indenting and
"   you change that line's indentation manually, Vim flags that line and will
"   no longer try to automatically define its indentation.
"   -When you paste text into your file where automatic indenting is turned
"   on, Vim considers this regular input and applies all automatic indentation
"   rules.
