The assertion I added on line 2626, which would ensure that the `RemoveBraces`
lambda on line 898 didn't miss any potentially removable braces, would fail
because `parseLevel()` was indiscriminately passing the `l_brace` of the last
`if` in the level to its caller. This new version is also a tiny bit more
efficient because `IfLBrace` on line 2624 will be null if the `else` block that
encloses the `if` block is not a simple block.
Because neither version would remove non-optional braces, I decided not to add
a test case just for the assertion, e.g.,
if (a)
b;
else {
c;
if (d) {
e;
f;
}
}
