Graphical emacsclient frames have modelines that look something like

U:    @---

instead of

U:@----

I cannot reproduce this.  Please show a full recipe starting from
"emacs -Q".

Thanks.

It seems to have something to do with the min-width display property.
When the client element is present, the default format is making the "U:"
element five chars wide instead of the entire "U:@---".

To experiment:

(setq mode-line-format
'("%e" mode-line-front-space (:propertize ("" mode-line-mule-info mode-line-client mode-line-modified mode-line-remote) 
              display (min-width (5.0)))
 mode-line-frame-identification mode-line-buffer-identification "   " mode-line-position (vc-mode vc-mode) "  " mode-line-modes mode-line-misc-info mode-line-end-spaces))

This doesn't show the extra spaces here.  Strange.

The following patch fixes the problem for me.

TBH I don't entirely understand why it fixes it (the code in xdisp.c
related to display properties is complicated). Apparently it has
something to do with properties calculated in advance vs calculated
in a :propertize form, which seems to affect what characters belong
to the min-width sequence.
