Thanks for the report. This bug still exists in 2.1.11. The following
patch is totally untested, but I think it will fix it for '_'. I'll
have to think about other non-alphanumeric characters. At least it
will point to the right place in the code.

Note that if you know there is an address with a leading '_', you can
display it with a find pattern of '^_', but this doesn't help if you
don't know. Also, if you didn't have the '6' address, the '_' address
would display on the default page.

Here's the patch:
