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.

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.

- Don't skip display() altogether, even if list == NULL.
- Don't skip the call to the printfn in display() if we
need to print the total.

compile-time option, where:
ps -options arg1 arg2
(with no '-' on "arg1" and "arg2") was treated as:
ps -options -N arg1 -M arg2
This also changes `ps' to check for any additional arguments after
processing all the '-'-options, and attempt to use those arguments as
a pid or pidlist. If an extra argument is not a valid pidlist, then
`ps' will print an error and exit. This seems a more generally useful
extension of the kludge-option processing than the -N/-M behavior, and
has fewer confusing side-effects.

This is an often-requested feature.
Use wcwidth() to determine the number of column positions a character

1 byte = 1 column position, e.g. line-wrapping when handling the -m option.
The error handling here is somewhat more complicated than usual: we do
