Redmine

I use svn, but I suppose it does not matter for this bug.
I've merged a sequence of revisions (from 1415 to 1420) to some branch.
I've added a message with the revision numbers like this:

svn commit . -m "Merging r1415-1420 to some branch." 

Now while everything is as it should to be in svn log:

------------------------------------------------------------------------
r1422 | kaltbregen | 2014-03-06 16:51:20 +0400 (Thu, 06 Mar 2014) | 1 line

Merges r1415-1420 from redmine-2.4.1-staging

In the web (projects/project_name/repository/revisions/1422) it is:

And though this is is a clickable hyperlink to projects/project_name/repository/revisions/1415, it should not hide hyphen and second number at all.
