So:
x = (cond) ? yes : no;
Where there are always parentheses around the condition, even if not
required for disambiguity. Additional parentheses are always allowed,
but the parenthesized condition helps signal that a ternary operator is
coming earlier in the expression.
This style has grown on me as I think it helps code readability. It
reminds me of the required parentheses for if/while statements.
Might as well adopt codebase-wide.
The size field in lfs_info doesn't really make sense for stat/dir_read
when the file is a directory. Still, we should probably set it to 0 os
it's not uninitialized.
Fortunately we were already setting size=0 in _most_ cases, this commit
is mostly just checking for size=0 in more test cases.
