[PATCH 03/15] record-btrace: fix insn range in function call history

[Markus Metzger <markus.t.metzger@intel.com>]

With the "/i" modifier, we print the instruction number range in the
"record function-call-history" command as [begin, end).

It would be more intuitive if we printed the range as [begin, end].

2013-05-02  Markus Metzger  <markus.t.metzger@intel.com>

	* record-btrace.c (btrace_call_history_insn_range): Print
	insn range as [begin, end].
