odd behavior in stap statement probes with varied wildcards

[BR Chrisman <brchrisman at gmail dot com>]

Description:
statement("*@<file>:<line>") *doesn't* find the probe point
statement("<function>@<file>:<line>") *does* find the probe point.
statement("*@<file>:*") *does* find the probe point (grepped)
statement("*@<file>:0,<line>") *does* find the probe point
statement("*@<file>:<line>,<line>) *does* find the probe point

Theory: Possible interaction bug with the wildcarding between function
specifier and line number specifier which is somehow overridden with
comma-separated line specifier or line-number wildcarding.

I'm a bit familiar with this code, so I can put some eyeballs on it.

This is a transcript that I've modified just to simplify the binary
name to 'Binary', the source file to 'foo.h', and the function name to
'myfunction' from their original (very unreadable) values.
