    Add missing braces around else clause in Read_Quoted()
    
    Found by gcc 7.3:
    
    xprop.c: In function ‘Read_Quoted’:
    xprop.c:163:8: warning: this ‘else’ clause does not guard... [-Wmisleading-indentation]
          } else
            ^~~~
    xprop.c:164:17: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘else’
       ptr++[0] = c; length--;
                     ^~~~~~
    
    Introduced in initial commit to X Consortium RCS in 1987:
    https://cgit.freedesktop.org/~alanc/xc-historical/commit/xc/programs/xprop/xprop.c?id=18ea83d7457743936e99a574b50e208f7697f096
    
    Actual effect is minimal - for every \-escaped newline in the DFORMAT
    portion of a xprop formats file, xprop subtracted one byte too many
    from the count of bytes still available in the buffer, which could lead
    it to return an error of "Bad format file format: dformat too long." when
    there was still room left.  Since the original buffer size was 10,000
    bytes, and the current size is 500,000 bytes, it's unlikely anyone ever
    hit this in real usage.
