It's a change made in several PHP files. The chances that the same patch can be applied to REL_1_5 are slim, but check the CVS announce list's archives - http://mail.wikipedia.org/pipermail/mediawiki-cvs.
At first sight, it appears to be a fairly simple change - namely this one: http://mail.wikimedia.org/pipermail/mediawiki-cvs/2006-January/013156.html
However, just that on its own isn't enough; it seems that the legal title chars are now a configuration option, so you have to add "+" to that list as well. But that list doesn't exist in version 1.5, so you will have to do some hacking after all, and there may have been other changes when that was first made configurable...
