4 * The indentation of the very first line of a file determines the
5 * indentation of the remaining code. Even if later code has a smaller
6 * indentation, it is nevertheless indented to the level given by the first
7 * line of code.
8 *
9 * In this particular test, the indentation is set to 5 and the tabulator
10 * width is set to 8, to demonstrate an off-by-one error in
11 * main_prepare_parsing that has been fixed in indent.c 1.107 from 2021-10-05.
12 *
13 * The declaration in the first line is indented by 3 tabs, amounting to 24
14 * spaces. The initial indentation of the code is intended to be rounded down,
15 * to 4 levels of indentation, amounting to 20 spaces.

31 * In the above function declaration, the space between '){' is missing. This
32 * is because the tokenizer only recognizes function definitions if they start
33 * at indentation level 0, but this declaration starts at indentation level 4,
34 * due to the indentation in line 1. It's an edge case that is probably not
35 * worth fixing.
