[CWEB] Make room for larger index entries.

At the time when DEK created CWEB and CTWILL, C compilers restricted the
length of 'identifiers', e.g., variable and function names.

In more recent years, programmers are enjoying the freedom to use more
descriptive names in their sources.

In order to apply 'refsort' to Martin Ruckert's HiTeX ('typedef word_file'
in line 2583 of 'hitex.w') and to Scott Prahl's 'Inverse Adding-Doubling'
(function 'Calculate_Distance_With_Corrections' in line 1124 of 'iad_calc.w';
see https://github.com/scottprahl/iad; this is the first 'off-brand'
application of CTWILL I've seen in the wild!), we moderately extend the
relevant parameters.
