lsvfs: restyle, no functional change
Namely: - main was using two-space indentation - re-sort local variables - explicit braces for loop scope - make flag bit comparison explicit The first line of this commit message is unfortunately a lie, as it introduces a minor functional change on non-FreeBSD systems. Namely, the first branch is now explicitly compared against `0` and the choice was made to compare it as greater than 0 to avoid issues on other systems where `argc != 0` on entry isn't guaranteed (negative when checked there).
