0c77b3c9c1 o Terminate an endless loop sh -T goes into in dowait() around waitproc().
XXX from Tor: "The shell can also go into a similar loop if the child was
killed by signal 127, since the shell would believe the child to have
only stopped (WIFSTOPPED() macro returns nonzero value).  Disallowing
signals 127 and 128 will fix that problem."  See kern/19402 for details.

24c0f7385b Add -I, an option that asks for confirmation once if recursively
removing directories or if more than 3 files are listed in the
command line.

This feature is intended to provide a safe net but not being too
annoying like having "rm -i" for every deleting operations, and
is generally good for both newbies and power users, preventing
them from being so easily run into ``rm -rf /'', ``rm -rf *''
and so forth.

Originally implemented by Matthew Dillon for DragonFly, plus
some improvements done by various DragonFly contributors.

3f91ab9262 The previous commit added code to rm(1) to warn about and remove any
occurrences of "/" in the argument list.  This corresponds to Enhancement
Request Number 5 in the Austin Group TC2 Aardvark's XCU Defects Report
(<URL:http://www.opengroup.org/austin/aardvark/finaltext/xcubug.txt>).
Further discussion is available in the Austin Group mailing list archives
(<URL:http://www.opengroup.org/austin/mailarchives/>, "Defect in XCU rm")
and for Austin Group members, in the Austin Group Interpretations archive
(<URL:http://www.opengroup.org/austin/interps/>, AI-019)

This commit makes that check conditional on !POSIXLY_CORRECT, since it
is not strictly correct according to the current version of the standard
(but is expected to be correct according to the next version, and has
already been adopted by Solaris).

e3edab4a91 Add a "fillchar" command line argument to dd(1) that permits the user
to specify an alternative padding character when using a conversion
mode, or when using noerror with sync and an input error occurs.  This
facilities reading old and error-prone media by allowing the user to
more effectively mark error blocks in the output stream.

d3e240cb45 Change the behaviour of `-v' so that, e.g., stepping a month back
on March 31 won't take you to March 2 or 3 (now the result will
be the last day of February.)

In general, now stepping by months from the last days of the current
month A will take you to the very last day of the target month B if
B is shorter than A.

The previous version would just step to March 31 and rely on mktime(3)
to correct the date.  Despite its simplicity, such way was counter-intuitive
to users and caused pain to shell script writers.

239c9e601a Currently if a mount point is not accessible by the calling user,
invalid information will be printed if the -t flag is specified.

$ df -t ufs
Filesystem  1K-blocks     Used    Avail Capacity  Mounted on
/dev/ad0s1a    495726   139944   316124    31%    /
/dev/ad0s1e    253678     6438   226946     3%    /tmp
/dev/ad0s1f  56206340 13594248 38115586    26%    /usr
/dev/ad0s1d    694126    19812   618784     3%    /var
/dev/ad0s1d    694126    19812   618784     3%    /var
$

Note that the mount point which is not accessible shows
up as the previous file system that was printed. The reason
for this is that df -t will call statfs(2) on the pathname
supplied by getfsstat(2).

This is done to refresh the file system statistics in the
event that a previous file system had a long delay in
providing its stats.

This change affects the df utility in the following ways:
o Teach df has to deal with statfs(2) failing. If statfs(2)
  fails, fall back on the possibly stale stats provided by
  the initial call to getfsstat(2).
o Print a warning that the fs stats could possibly be stale
o Modify the man page and document this new behavior
  as a bug.
