    paste: fix warning on indentation in parallel()
    
    _Bug_
    Got the following error after cloning and running make:
    
    paste.c: In function ‘parallel’:
    paste.c:70:4: warning: this ‘else’ clause does not guard... 
[-Wmisleading-indentation]
        else
        ^~~~
    paste.c:72:5: note: ...this statement, but the latter is misleadingly 
indented as if it is guarded by the ‘else’
         last++;
         ^~~~
    This patch preserves the same functionality and just adjusts indentation to 
squelch the warning.
    
    _Test plan_
    Used the following 'script' to convince myself output looked correct for 
inputs
    where the latter arguments to paste had fewer lines.
    
        make && printf "1\n2\n" > two.txt && printf "" > zero.txt && ./paste 
-d, two.txt zero.txt
