Use echo to see what rsync thinks it is getting.

    [test at colug hornsby]$ echo rsync '*'
    rsync *
    [test at colug hornsby]$ echo rsync "*"
    rsync *
    [test at colug hornsby]$ echo rsync *
    rsync foo
    [test at colug hornsby]$ 

Or use something like my showargs 
to see what rsync thinks it is getting.

    [test at colug hornsby]$ cat ~/util/showargs.c 
    #include <stdlib.h>
    #include <stdio.h>
    
    int main(int argc,char *argv[])
    {
       int i;
    
       for (i=0;i<argc;i++)
          printf("argv[%d]=\"%s\"\n",i,argv[i]);
    
       return EXIT_SUCCESS;
    }
    
    [test at colug hornsby]$ ~/util/showargs rsync '*'
    argv[0]="/home/jep/util/showargs"
    argv[1]="rsync"
    argv[2]="*"
    [test at colug hornsby]$ ~/util/showargs rsync "*"
    argv[0]="/home/jep/util/showargs"
    argv[1]="rsync"
    argv[2]="*"
    [test at colug hornsby]$ ~/util/showargs rsync *
    argv[0]="/home/jep/util/showargs"
    argv[1]="rsync"
    argv[2]="foo"
    [test at colug hornsby]$

By the way, that first double quote is not the same as the 
second double quote. Your first double quote character is a 
three byte sequence E2 80 9C in UTF-8. I think to a shell, 
that's just another character, not a double quote.
    
    [test at colug hornsby]$ echo '—include=“*.log-2015-*"' | xxd -g 1 -u
    0000000: E2 80 94 69 6E 63 6C 75 64 65 3D E2 80 9C 2A 2E  ...include=...*.
    0000010: 6C 6F 67 2D 32 30 31 35 2D 2A 22 0A              log-2015-*".
    [test at colug hornsby]$ 

Is that how you sent the email?
