Use os.PathListSeparator for list of folders in cmd-line args

[wayoda]

Being able to specify arbitrary folders for libraries is a nice feature, but please don't use the comma to separate the items in a list of folders.

Use the platform independent os.PathListSeparator (: on unix, ; on windows).

Why?

• every commadline tool I know of does it that way. Users expect to seperate different paths by their local path separator character
• Go has a function to split a list of folders based on the os.PathListSeparator constant

Comma is the default way for the flag package. However, flag also supports multiple args of the same type. So, writing -hardware folder1,folder2 is the same thing as -hardware folder1 -hardware folder2

This is the preferred way of providing params as it allows to use terminal autocompletion when available

Uhm I was wrong about the "default way". I'll fix it. Still, don't use that syntax. Specify multiple -hardware params (or -tools, or -libraries or -prefs)
