What does that even mean?

* it requires one but doesn't use it by default

* it requires one but if none is present, falls back to stdio

* it simply checks for tty presence and uses something completely different

* something else

Btw, acme, those use_browser values could use proper defines like:

#define PERF_BROWSER_NONE	0
#define PERF_BROWSER_TUI	1
#define PERF_BROWSER_GTK	2

or even an enum or whatever else comes natural in perf-speak.
