There were two more minor problems with this patch:

   * You used <ctype.h> but it is better to use "safe-ctype.h" and
     replace the call to isdigit with a call to ISDIGIT.

   * You forgot to update Makefile.am to add a dependency for corefile.o
     upon ctype.h (or safe-ctype.h).

I have taken care of these two problems and applied your patch along 
with this ChangeLog entry.

Cheers
