- Added a few more scanf() tests.

- The __open_iob() function can be made simpler still.

- Changed the error abort condition for the %s conversion of the
scanf() family. It now matches the abort conditions for all other
conversions and no longer ignores whether any other parameters were
converted before. This was a quirk in the older implementation.

- The scanf() family now accepts %E and %G in place of %f and %X in
place of %x.

- Simplified the common code that fopen(), freopen() and fdopen()
share and which has to figure out by looking at a file access
mode specification which parameters should be used.

c.lib 1.181 (26.10.2004)

- The scanf() family now always returns the number of assignments made
unless an error occured or an EOF was hit during conversion before the
first assignment could be made.

- strtok() did not terminate properly if the last token in the string
did not end with a separator character but with a '\0' byte. Fixed.

- The directory scanning functions opendir/closedir did not get the global
directory data tracking data structure initialized which later led to
Enforcer hits and maybe trashed memory. Fixed.

c.lib 1.180 (23.10.2004)

- The printf() family now produces no output at all for %e, %f and %g if the
floating point support code is disabled. Previously, a minimum field width
specification could take effect, printing a series of 0 or blank space
characters where no output should have been produced.
