 * The indentation of the very first line of a file determines the
 * indentation of the remaining code. Even if later code has a smaller
 * indentation, it is nevertheless indented to the level given by the first
 * line of code.
 *
 * In this particular test, the indentation is set to 5 and the tabulator
 * width is set to 8, to demonstrate an off-by-one error in
 * main_prepare_parsing that has been fixed in indent.c 1.107 from 2021-10-05.
 *
 * The declaration in the first line is indented by 3 tabs, amounting to 24
 * spaces. The initial indentation of the code is intended to be rounded down,
 * to 4 levels of indentation, amounting to 20 spaces.
