Frequently when profiling multiple threads, I need to combine several dump stat files. Currently -m pstats reads the profiling data at only the first path given. It should merge all the profiling data from all the paths given.

$ python3.3 -m pstats prof/5506-7f00f*

Minimalist patch attached.

This sounds like a reasonable request.  The patch needs tests, probably using test.script_helper.assert_python_ok.

New changeset 3a5a0e7d38c5 by Antoine Pitrou in branch 'default':
Issue #13839: When invoked on the command-line, the pstats module now accepts several filenames of profile stat files and merges them all.

I've committed the patch. Eric, adding a test suite for pstats' command-line interface is a separate concern.
