aa52177fb5 Dedocument one of the BUGS listed in the last commit. The bug (needless
calculation of line numbers) never existed and the two bugs that made me
think it existed have been fixed (see recent commits about this date to
linenum.c:r.1.3 and ch.c:r.1.8 fixing broken line-number buffering and
braindead algorithms respectively).

e965d6a895 Rather than use an LRU-ordered circular list to store buffered data,
simply keep an index into the last access on the circular list and begin
searches at that point.  An LRU list is inappropriate here since the
vast majority of accesses will occur in the same order that the list
is created in.  The only case where an LRU is remotely useful here is when
reading from a file and the user is jumping to randomish positions and
constantly returning to some central position.  Even for this case it is
such a small optimization as not to be noticed in an interactive program
such as more(1).

This change results in a _tremendously_ noticable speed-up when reading long
files through a pipe (where long = ~200k, machine = ~2.5h single-disk
worldstone).

79bf951d43 Correctly maintain state when manipulating linked lists. This fixes a
bug that prevented the line-number buffer from working correctly.  AFAIK
the bug is still present in other derivatives of more(1).

to fix them.

20d6e5fe6e Thorough revamp of how input commands are processed. This allows customization
of user keys (documentation pending).  The only key whose semantics have
changed is the capital 'N' key, which now performs a repeat-search in the
opposite direction (just like in vi).

This commit is a little bulkier than what I had originally planned.  I'm not
completely happy with the direction it went, but it's definately an
improvement, and the alternative is to continue becoming irrelevant compared
to GNU less.  (Does anyone even _use_ /usr/bin/more these days?)

3be5f1f5ce Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

     .\"    $Id$
     .\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

296697bb16 - When trying to decide if $EDITOR == "vi", match against only the first
two characters of $EDITOR.  This allows things like "vim" and "vi -G"
  (although nvi would fail...oh well).

- Avoid certain cases where the editor is passed an invalid line number.

to the reported problem).

984e3edbe2 Make more not immediately exit on a short file, if the -e option is
given.  This makes more -e basically usable at all when your termcap
entry supports an alternate screen buffer (like xterm-r6).

I wonder whether we should make more -e the default.  Oure more seems
to be the only one on the world with this funny behaviour.
