Question:
Should "flag.commandLine" be exported similar to how
"http.DefaultServeMux" is exported?

Proposal:
Rename "flag.commandLine" to "flag.DefaultFlagSet". Include this in
Go1 because it's a backwards compatible change.

Use Case:
I'm writing a config file parser that uses a flag.FlagSet to determine what options are
allowed.

I would like to be able to write a function to operate on any "*flag.FlagSet"
including "flag.commandLine". The exact function I'd like to be able to write
is this:

func DoStuff(fs *flag.FlagSet) {
   if fs == nil {
      fs = flag.DefaultFlagSet
   }
   ...
}

Abuse Potential:
Not much. Someone could replace "flag.DefaultFlagSet" or set it equal to nil.
Neither would be a problem in practice.


If this is not a crazy idea let me know and I'll make a patch.
Thanks!
