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.
