functrace and funcgraph only supports single function

[alokprasad]

Currently, functrace and funcgraph only supports single function.
There might be cases when we need to monitor multiple function in single tracing.

I had to manually edit and multiple function using.

function1 >current_tracer
function2>> current_tracer

Hello!
I think you simply need to escape the filter string argument. Maybe also necessary if you use * in the function string, so that bash will not expand the argument.
funcgraph -m 3 'function1_* devX_function2'
