Emacs has fancy commands to vertically recenter,
C-l runs the command recenter-top-bottom.

But alas no command to horizontally recenter.

All it has are the commands on
(info "(emacs) Horizontal Scrolling") Not good enough.

"It's just not fair." "Thin is in, fat is shat."

The future horizontal-recenter command (please implement) should keep
the cursor upon the same character (x), but just move the view screen ([
]) so that x is now in the center.

......[.......x..]...... BEFORE
.........[....x.....]... AFTER

Also at the end of (info "(emacs) Recentering")
add

     The above all refers to vertical recentering. For horizontal recentering
     see (info "(emacs) Horizontal Scrolling").

And on (info "(emacs) Horizontal Scrolling") add the above newly
implemented command, and at the bottom of course mention:

     The above all refers to horizontal scrolling/recentering. For vertical recentering
     see (info "(emacs) Recentering").

P.S.,
[..x.......]..... BEFORE
[..x.......]..... AFTER
i.e., nothing, is probably what should happen if there is no room to
pull from the left.
P.P.S., each "." represents around 10 characters.

Good point.  I'm all for a horizontal recenter command (maybe disabled
by default).

Indeed.  This could be quite helpful in editing and viewing very long
lines.

So this would only be for buffers where truncate-lines is non-nil?  Yes,
it'd be handy to have such a command...  or perhaps `C-l' should just do
this automatically (in these buffers)?

Any opinions?

No, also in partial-width windows (as in after "C-x 3").

Since lines are generally not all of the same width, such horizontal
scrolling can only guarantee to center one line, and sometimes cannot
center it at all (if it's narrower than the window).  I wonder whether
the OP indeed understands what he will get as result of implementing
this feature.
