style(9)ify boot2.c

[benno]

Summary

Style fixup for boot2.c.

There's a one code change in parse() so the code fits inside 80 columns.

[imp]

So style(9) requires a blank line at the start of a function with no local variables. I tagged a couple, but there are more.

stand/i386/boot2/boot2.c

149

Blank line at start of function rule

189

blank line

351

this, and others, need parse(void)

[benno]

Added blank lines to the start of functions without variable declarations.
Removed assignments from variable declarations (except one that was static).

[imp]

lgtm, though I must admit to review fatigue

I think you could remove that clause from style(9) without (much? any?) objection, if you wanted to go through that whole mess to gather consensus.
