[Cocci] coccinelle & linux-kernel: unindent blocks by reversing tests?

[Joe Perches]

There are many blocks of code that could be
unindented and so neatened by reversing tests.

[]

Which often saves many vertical lines by reducing
now unnecessary line-wrapping done at 80-columns.

I tried it. One can't easily make the transformation when there is a
variable declaration in the block. And Coccinelle doesn't move leading
comments over to the left. Most of the examples I found seemed to have
only one level of opportunity. I don't know if the churn is worth it in
that case. On a more complex example, the pretty printer crashes, so I'll
have to look into that.

Dunno about the churn, but converting many lines of badly
wrapped simple statements and reducing line count seems
somewhat worthwhile.
