allow wildcard matching for file paths

[sstrong99]

It would be nice if you could specify matching filenames with wildcards instead of verbatim. This would be useful for example for files with timestamps in the name

Wouldn't it be easier to specify the output paths for such programs? Must programs have an "--output" or similar option that can be used to explicitly set the file path.

EDIT: More as a general statement: timestamps are hard to test. My preferred solution is to get rid of the timestamps rather than on complicating the test framework. A test framework should not have bugs, and complication is a liability for that reason.
