Hi misc@,
while trying to use indent(1) on my lsblk.c, I get the following two
errors:> Error@150: Stmt nesting error.
Error@702: Missing braces at end of file.
It also doesn't handle unicode and breaks horribly at some points.
I have attached both the origin and the indented version
as Thunderbird doesn't seem to wanna deal with so much text.
For now, I'm just gonna do it myself according to style(9).
Thanks,
Benjamin Stürz
