bug#73463: [PATCH] Align columns with wide characters properly

[Thomas Voss]

Hi all,

For a while I’ve been bugged by some behaviour in Which-Key.  My font of
choice is Iosevka — a font that is quite popular — and it chooses to make
the ellipsis character 2-columns wide.  This is typically not a problem,
but it causes Which-Key columns to appear misaligned as it truncates long
descriptions with the ellipsis by default when the user configures it to
use Unicode (and I rather enjoy the ellipsis).

This happens despite the following being in my init.el:

    (set-char-table-range char-width-table ?… 2)

After further investigation, this appears to be due to a simple usage of
‘length’ instead of ‘string-width’.  The following trivial patch attached
to this email seems to have solved this issue.
