"export tags" doesn't work well with import prefixes

[cgay]

I'm pretty sure the issue here is deeper than the export tags command, but that's the way the problem surfaces for me. If I use operating-system, prefix: "os/", the tags generated by the export tags command store this in the emacs TAGS file:

define function run-application^?run-application^A252,10341

Clearly emacs' M-. isn't going to find os/run-application in this TAGS file.
