[PATCH v2 1/7] gdb.perf/: Fix tcl_string_list_to_python_list {x}

[Ilya Leoshkevich via Gdb-patches <gdb-patches@sourceware.org>]

tcl_string_list_to_python_list {x} returns "(x)", which is not a tuple
(the valid tuple syntax would be "(x,)").  Instead of special-casing
this, just change the function to return what its name says: lists.
This way in the problematic case we will get "[x]".
