 via profile startup files

Hello, 宋文武!

As the author of [1] I might be a bit biased, but I have a few
questions regarding this patch set:
1. Will it correctly pick up IM_MODULE_FILEs at system level if you
also happen to have GTK+ applications installed at user level?
  a. What about multi-profile setups, where more than one profile
contains GTK+ applications?
  b. What about `guix environment`?
2. Which purpose would sourcing those files offer other than setting
environment variables?  What would be permissible actions?  Remember,
that those would be executed whenever the user spawns a shell, so while
you could put stuff like `fc-cache -r` in there, I personally think you
ought not to.

I believe a proper fix for GTK would be to allow setting multiple
IM_MODULE_FILEs instead of a single one and using search paths.  [1]
was merely meant to have a reasonable default when installing ibus
system-wide, it can not (and will not) help you if you also happen to
have stuff in another profile.

Regards,
Leo
