Title: improve alpha sort in mflag

```
go run example.go -h
--integer, --number=-1: a simple integer
-b=false: a simple bool
-h, --help=false: display the help
-s, --string="": a simple string
```

becomes:

```
o run example.go -h
-b=false: a simple bool
-h, --help=false: display the help
--integer, --number=-1: a simple integer
-s, --string="": a simple string
```

will be useful in #4174 (@vbatts) and #4441 (@crosbymichael)
