This seems to have caused a couple of BF failures on Windows (sorry
for my role in hiding those, I've just been reviewing all failures to
atone):

Excerpts:
# debug(script=0,command=31): double 8.50705917302346e+037
# doesn't match '(?^:command=31.: double 8.50705917302346e\+37\b)'
# debug(script=0,command=32): double 1e+030
# doesn't match '(?^:command=32.: double 1e\+30\b)'
The difference seems to be a leading zero before the exponent, so
perhaps the patterns need "0*" in there?
