Akim Demaille 89c4e1becf scanner: avoid spurious errors about empty character literals ...

On an invalid character literal such as "'\777'" we used to produce
two errors:

    input.y:2.9-12: error: invalid number after \-escape: 777
    input.y:2.8-13: error: empty character literal

Get rid of the second one.

* src/scan-gram.l (STRING_GROW_ESCAPE): New.
* tests/input.at: Adjust.
