As mentioned in 'Generating optimal glyphs' title in the manual page

Where a proper caret (^) that renders well in both a terminal and PDF is
required, use "\(ha".
Using a naked "~" character results in a poor rendering in PDF. Instead
use "\(ti".

When readline is called to get user input, it is called without
a prompt argument. As a result, if the user does not enter anything
for a given field, then the next field is displayed on the same
line, yielding the following output:
$ chfn
Changing finger information for user.
Password:
Name []: Office []: Office Phone []: Home Phone []:
instead of the expected:
$ chfn
Changing finger information for user.
Password:
Full Name []:
Room Number []:
Work Phone []:
Home Phone []:
This patch restores the expected behavior by feeding readline with
a character to display as "prompt".

There is value in ensuring that manual page sections use consistently
named sections, as far as possible, and also that sections have a
consistent order within manual pages. This is one of a series of patches

In this patch, we ensure that the NOTES, HISTORY, BUGS, and EXAMPLE
sections are always placed near the end of the page, just above
AUTHORS, COPYRIGHT, SEE ALSO, and AVAILABILITY.
One page is not fixed by this patch: term-utils/agetty.8. This page

Using double quotes in .SH lines containing multiple words is unneeded,
and in any case is not consistently done in the util-linux manual pages,
where double quotes are used in only around half of the cases.
(This usage was long ago elminated in the man-pages project, with
no ill effects reported to date.)
Remove these quotes, so that .SH lines are more uniform, in preparation
for some (more easily) scripted doiscovery of consistency problems in
(and possibly global fixes to) the manual pages.
Other than stripping the double quotes, this patch makes no changes to
the content of the manual pages.

The current default behavior is to print the first issue file/dir and
all alternative locations are used as a backup solution only. If something
is found than the rest is ignored. The --issue-file allow to overwrite
this default behavior, but currently it supports only one file/dir.
This patch extend --issue-file to support ':' separated list of paths
and *all* the files (if exist and no empty) in the list are printed.

With users coming from LDAP, it is often the case that the entry in LDAP
does not contain one or more attributes required by su or, because of
misconfigured access control rights, the attribute might not be readable
by the LDAP client. In that case, su just tells the user that the user
does not exist.
It might be more user-friendly to tell the user to check the user entry
for all required fields.
