Fix a bug with the last item in CLI history getting duplicated when

Browse Source 
read from the .asterisk_history file (and subsequently being duplicated
when written).  We weren't checking the result of fgets() which meant
that we read the same line twice before feof() actually returned non-

Also, stop writing out an extra blank line between each item in the
history file, fix a minor off-by-one error, and use symbolic constants
rather than a hardcoded integer.
