Without modifiers, it prints the function name.\n\
With a /l modifier, the source file and line number range is included.\n\
With a /i modifier, the instruction number range is included.\n\
+With a /c modifier, the output is indented based on the call stack depth.\n\
With no argument, prints ten more lines after the previous ten-line print.\n\
\"record function-call-history -\" prints ten lines before a previous ten-line \
