Here is the patch. I had to create a global variable
cc_t backup_intr_char
to record what the interrupt character was initially, since nano turns it
off in main().
I also took the opportunity to create an nperror wrapper function for
perror. Builds character to check system call return values. Perhaps the
contents of nperror should be wrapped in #ifdef DEBUG.
I wonder if we could make a similar ^C feature when loading or writing a
file. I guess that would take more work, since it would need the
cooperation of the file-loading code. The signal handler would merely set
a CANCEL_ACTION flag, and periodically the read or write code would
examine the flag, and stop if it was set.
