[PATCH 1/5] diagnostics: use grammar_file instead of current_file

[Akim Demaille]

Currently there are two globals denoting the input file: grammar_file
is the one from the command line, and current_file which might change
because of #line.  Use only the former.

* src/complain.c (error_message): here.
* tests/diagnostics.at: Adjust.
