Theophile Ranquet c1b2677ad0 scanner: reintroduce unput for missing end tokens ...

Unput was no longer used since a POSIX-compatiblity issue with Flex 2.5.31,
which has been adressed in newer versions of Flex.  See this discussion:
<http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00029.html>

This partially reverts commit aa4180418f.

* src/scan-gram.l (unexpected_end): Here.
* tests/input.at: Adjust for new order of error reports.
