As do I, but perhaps coding style in a project like this
shouldn't be personal but collective.

The trailing style outnumbers the leading style ~ 5:1.

$ grep -rP --include=*.[ch] "(\|\||&&)[ \t]*$" * | wc -l
39890
$ grep -rP --include=*.[ch] "^[ \t]*(\|\||&&)" * | wc -l
8244

If you take out drivers/staging, trailing is used ~ 6:1.

I think that high enough to be declared the preferred style.
