webbrowser._iscommand(): is there a public version?

[Daniel Yoo]

Hi everyone,


I was curious to know: does the functionality of webbrowser._iscommand()
live anywhere else in the Standard Library?

webbrowser._iscommand() is a helper function that searches through
PATH, and seems useful enough that I was surprised that it didn't live
in a more public place like os.path.

Thanks!
