[PATCH] Some stftime.3 and nl_langinfo.3 updates

[Eugene Syromyatnikov <evgsyr@gmail.com>]

Hello.

There are some additions that cross-link these two pages and aim to make
the behaviour of a libc more clear with respect to locale-dependent
conversion specifications.  It is based on POSIX[1], GNU C Library
documentation[2], and glibc's implementation[3], with some
cross-checking of uClibc, musl, and FreeBSD implementations.

[3] https://sourceware.org/git/?p=glibc.git;a=blob;f=time/strftime_l.c

Eugene Syromyatnikov (7):
  nl_langinfo.3: mention the respective strftime conversion
    specifications
  nl_langinfo.3: add information about AM/PM time format locale elements
  nl_langinfo.3: document era-related locale elements
  strftime.3: ffix
  strftime.3: consistently document fall-back format string
  strftime.3: refer to the relevant nl_langinfo items
  strftime.3: expand %E and %O description
