diff toys/posix/kill.c @ 694:786841fdb1e0

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Reindent to two spaces per level. Remove vi: directives that haven't worked right in years (ubuntu broke its' vim implementation). Remove trailing spaces. Add/remove blank lines. Re-wordwrap in places. Update documentation with new coding style. The actual code should be the same afterward, this is just cosmetic refactoring.
