Valtteri> x-win.el should probably add a second regexp to the alist, such
as:
Valtteri> (add-to-list 'display-format-alist
'("\\`\\[[^]]*\\]:[0-9]+\\(\\.[0-9]+\\)?\\'" . x))
That regexp won't work, since now youʼre requiring the '[' and ']' to
be present.
"\\`\\[?[^]]*\\]?:[0-9]+\\(\\.[0-9]+\\)?\\'" would fix that, but since
we donʼt really care what comes before the ':', so would
"\\`.*:[0-9]+\\(\\.[0-9]+\\)?\\'"
