Prompted by a suggestion from Kalle Olavi Niemitalo
in http://bugs.debian.org/207035.
(direct_mode): New function.
(do_wipefd): Turn on direct-mode I/O.
(dopass): If a file's first write fails with EINVAL,
turn off direct-mode I/O and retry the write.

The POSIX SYNOPSIS does not allow this option combination.

where 'dd' created a file that was too large. The bug was that dd
assumed that the input file offset does not advance after a failed
read; but POSIX says that the input file offset is undefined after
a failed read.
(MAX_BLOCKSIZE): New macro.
(input_seekable, input_seek_errno, input_offset,
input_offset_overflow): New vars.
(scanargs): Reject block sizes greater than MAX_BLOCKSIZE.
(advance_input_offset): New function.
(skip_via_lseek): Set errno to zero when reporting our failure,
so that we don't report based on garbage errno.
(skip): If fdesc is standard input, advance the input offset.
Do not quit if reading, and if noerror was specified;
POSIX seems to require this.
If read fails on output file, report the earlier lseek failure
instead; this fixes a FIXME in dd_copy.
(advance_input_after_read_error): New function.
(dd_copy): Use it, instead of assuming that failed reads
do not advance the file pointer. Advance input offset
after nonfailed reads. Advance only a partial block if
the previous read (before the failed read) succeeded, and
do not generate an output block of zeros in this case.
(main): Determine initial input offset, seekability of input,
and error if it wasn't seekable.

remove a symlink to a file on an off-line NFS-mounted partition.
Reported by David Howells in https://bugzilla.redhat.com/124699.
(write_protected_non_symlink): New function.
Don't invoke euidaccess on symlinks.
(prompt): Use write_protected_non_symlink rather than using
euidaccess directly, being careful not to call lstat twice for a file.

abutting byte or character ranges. Reported by David Krider in
http://lists.gnu.org/archive/html/bug-coreutils/2004-05/msg00132.html
(print_kth): Remove special case for open-ended range.
(set_fields): Record the range start index for an interval even
when it abuts another interval on its low side.
Also record the range start index of the longest right-open-interval.

we need to test this in just one place now.
(usage): Mention -C.
(unquote): Note that \055, \n, etc are escaped.
Do not worry about POSIXLY_CORRECT when warning about ambiguous
escape sequences.
\ at end of string stands for itself.
Do not diagnose invalid backslash escapes: POSIX says the behavior
is unspecified in this case, so we don't need to diagnose it.
(main): Add support for -C (currently an alias for -c).
Do not diagnose 'tr [:upper:] [:upper:], as POSIX does not require
a diagnostic here.
