ecpg: fix more minor mishandling of bad input in preprocessor.

Don't get confused by an unmatched right brace in the input.
(Previously, this led to discarding information about file-level
variables and then possibly crashing.)

Detect, rather than crash on, an attempt to index into a non-array
variable.

As before, in the absence of field complaints I'm not too
excited about back-patching these.

Per valgrind testing by Alexander Lakhin.
