18 % Custom width parameters for TOC
19 % - Redefine low-level commands defined in report.cls.
20 % - Indent of 2 chars is preserved for ease of comparison.
21 % Summary of changes from default params:
22 % Width of page number (\@pnumwidth): 1.55em -> 2.7em
23 % Width of chapter number: 1.5em -> 2.4em
24 % Indent of section number: 1.5em -> 2.4em
25 % Width of section number: 2.6em -> 3.2em
26 % Indent of subsection number: 4.1em -> 5.6em
27 % Width of subsection number: 3.5em -> 4.3em
28 %
29 % These params can have 4 digit page counts, 3 digit chapter counts,
30 % section counts of 4 digits + 1 period (e.g., 18.10), and subsection counts
31 % of 5 digits + 2 periods (e.g., 18.7.13).
