Better yet, fix the threading as well.  Apparently, that webmail service
you're using is incapable of that, so use another.

Possibly they are, but you had also identified the specific positions
for 14 out of 20 characters.  You appear to have recalled incorrectly,
and checking for other possible orderings of characters in the entire
20-character string is a lot more effort.  For example, if we know all
of the 20 characters and know each character appears exactly once, but
we have no idea what order they're in, then that keyspace is way too
large for us to search (thousands of years even with multiple GPUs).  So
we absolutely have to include some knowledge about positions of some of
the characters, yet you appear to have failed to recall that reliably.

I've tried removing the requirement for one of []{} by commenting out
these lines in AdrianReq:

	if (!(mask['[' >> 5] & (1 << ('[' & 0x1f))) &&
	    !(mask[']' >> 5] & (1 << (']' & 0x1f))) &&
	    !(mask['{' >> 5] & (1 << ('{' & 0x1f))) &&
	    !(mask['}' >> 5] & (1 << ('}' & 0x1f)))) {
		word = 0;

This didn't help:
