It is such only before starting the inferior.  Normally select_frame() always
sets current_language according to the frame chosen right now.

Also in some cases language is passed along structures (such as struct
breakpoint) and functions.

IMO this problem is only for object files which is mostly just a problem for
hackers.  And for gdb testsuite.  But I agree some better autodetection would
be nice.  But only for the case of single objfile (and possibly single CU) to
make the code simple IMO as it gets never used otherwise anyway.
