Fix compile time warning for input-file.c

[Nick Clifton]

Hi Guys,

  I am applying the patch below to remove the compile time warning
  about an implicit declaration of the function 'isspace' and
  incidentally switch over to using ISSPACE instead.

Cheers
        Nick

        * input-file.c: Include safe-ctype.h.
        (input_file_open): Use ISSPACE instead of isspace.
