Forget previous 099u patch...
It was mangled.
Attached is a correct version.

Don't say I didn't warn you.

Reimplement mkdirhier; see Debian #141347 and #232357 for some reasons why.

.SH NAME
-mkdirhier \- makes a directory hierarchy
+mkdirhier \- create a directory hierarchy
.SH SYNOPSIS
.B mkdirhier
-directory ...
+.I directory
+\&...
.SH DESCRIPTION
-The
-.I mkdirhier
-command creates the specified directories. Unlike
-.I mkdir
-if any of the parent directories of the specified directory
-do not exist, it creates them as well.
+.B mkdirhier
+creates the specified directories.
+Unlike some versions of
+.BR mkdir ,
+if any of the parent directories of the specified directory do not exist,
+.B mkdirhier
+creates them as well.
+.PP
+.B mkdirhier
+is a wrapper for
+.BR mkdir ;
+systems with
+.BR mkdir (__osmansuffix__)
+implementations conformant with the Single Unix Specification may simply
+use
+.B mkdir \-p
+instead \(em this includes all systems using the GNU Core Utilities'
+version of
+.BR mkdir .
+.SH DIAGNOSTICS
+If
+.B mkdirhier
+is not supplied with any arguments, a usage message is printed.
+.PP
+.B mkdirhier
+prefixes its diagnostic messages with the name under which it was invoked,
+followed by a colon (\(oq:\(cq) so that its messages can be distingushed
+from others.
+.TP
+.B could not create directory \(dq\fIdirectory\fP\(dq
+indicates that there was a failure while creating
+.IR directory .
+This message will likely be preceded by a diagnostic message from
+.BR mkdir .
+.SH "EXIT STATUS"
+.TP
+.B 64
+.B mkdirhier
+was not given any directory names to create.
+.PP
+.B mkdirhier
+otherwise exits with the exit status of the last
+.B mkdir
+command that failed.
+.SH BUGS
+.B mkdirhier
+does not create all the requested directories as an atomic operation;
+therefore, it is is susceptible to race conditions.
+For example, if
+.B mkdirhier
+is directed to create a hierarchy
+.I a/b/c/d
+and any of
+.IR a/ ,
+.IR b/ ,
+or
+.I c/
+do not yet exist, any of the newly-created directories can be removed
+and/or replaced by a symbolic link to another location in the window of
+time after
+.B mkdirhier
+creates a directory and the directory immediately below it.
+This means that failures can be provoked (since
+.B mkdir
+will fail to create a directory in a directory that does not already
+exist),
+or directories may be created in unexpected locations.
+The same limitation holds for multiple directory arguments to
+.BR mkdirhier ;
+given two arguments
+.I a/b/c/d
+and
+.IR a/b/c/f ,
+it is possible for the directory hierarchy
+.I a/b/c
+to be disrupted in the time between the processing of the two arguments.
+To avoid these problems, use
+.B mkdir \-p
+instead, or do not use
+.B mkdirhier
+to create directories in parts of the filesystem where untrusted users can
+manipulate them.
.SH "SEE ALSO"
-mkdir(1)
+.BR mkdir (__osmansuffix__)

+# I rewrote Paul Eggert's script in POSIX shell because it was a little
+# odd, and did not confine itself to puritantical pre-POSIX conventions.
+# For example, in one place it used:
+# case ${1--} in
+# -*)
+# to test for $1 being null, presumably due to fears that test -n and -z
+# will not be available. Yet later in the script, test -n was used.
+#
+# This seemed quite silly. I decided to rewrite it since I am arrgoant
+# enough to think I know what I'm doing in POSIX shell.
+#
+# If someone needs a pre-POSIX version of mkdirhier, they'll probably need to
+# turn to someone else, as I have no idea where such a thing is specified.
