main: Simplify code that deals with early user input

Browse Source 
A read stream will be started before the first ex command is processed. This
stream will be used to read early user input before handling control over to the
UI module.

Which stdio stream will be used depends on which types of file descriptors are
connected, and whether the "-" argument was passed.
