Added a description of the "-E" command-line option to cl65's document.
Improved other descriptions, to make them more consistent and accurate.

This option is passed to the cc65 compiler; and, it forces cl65 to stop

If the <tt/-o/ option isn't used, then the C code results are written into

the C64 as a target system by default. This was chosen since most people
