The original code was 'for (;;) {...}', where ... ended
with a 'return -2' statement and did not contain a 'break' or 'continue'
statement.  Therefore, the body of the loop is always executed once.

Once upon a time there was a 'continue' in the loop, but it was removed in
rev36346, committed by mwh on Wed Jul 7 17:44:12 2004.

(I asked the BDFL first, and he approved removing it.  The last actual bugfix
to Tools/modulator was in 2001; since then all changes have been search-and-replace:
string methods, whitespace fixes, etc.)
