whether stdin is seekable, because lseek silently fails on
some special files, like tty's.

* tac.c: Change +regexp to +regex for consistency with GNU find.
* cp.c (copy_dir): Initialize 'ret' to 0.

Make -i override -f and -o, to be conservative about
removing peoples' files.

(longdiff): Macro to compare two longs efficiently if sizeof
int == sizeof long and less efficiently but correctly if they

summary directory size printed by -l to be in 1k blocks
without having the size of each file printed as well.
(convert_blocks): Provide for systems with a blocksize that is
other than 512 or 1024 bytes.
* du.c (main): Exit with status 0 normally.
(convert_blocks): Provide for systems with a blocksize that is
other than 512 or 1024 bytes.
Wed Jun 20 01:52:02 1990 Brian Fox (bfox at albert.ai.mit.edu)

Wed Jun 20 01:46:09 1990 David J. MacKenzie (djm at albert.ai.mit.edu)
* cat.c (cat): If FIONREAD is available, only use it if it is
supported by the filesystem that the file is on.
* ln.c (do_link): Take out code to give an error if source and
dest are the same file. The dubious usefulness of the special
case to prevent 'ln x x' from removing 'x' (ln -i can be used
instead) is not worth preventing 'ln x y' from failing the
second time in a row, and appears to contradict POSIX anyway.
Mon Jun 18 02:48:17 1990 David J. MacKenzie (djm at apple-gunkies)
* ls.c (print_file_name_and_frills,
length_of_file_name_and_frills, print_long_format):

* argmatch.c (invalid_arg): Change order in which the items

prevent buffer overruns.

purpose. Only do the check for regular files.

Wed May 30 15:34:47 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
* cut.c (main) Don't dereference 0 while parsing args.

Tue May 22 00:56:51 1990 David J. MacKenzie (djm at albert.ai.mit.edu)

the switch statement, so all file types are copied correctly
even in a non-recursive copy.

chmod and utimes dereference, and would affect the symlink
target. Remove test for symlinks after switch.
Sun Feb 25 18:31:09 1990 David J. MacKenzie (djm at albert.ai.mit.edu)

shell file completion but the rmdir syscall can't handle them).

Fri Feb 9 10:25:03 1990 David J. MacKenzie (djm at rice-chex)
