bug#24101: 24.5; incorrect double-click selection in cperl-mode

[Clément Pit--Claudel]

Thanks; I can reproduce this on master. Calling word-at-point on "2" shows the 
same problem (it doesn't include "1").
The problem seems to be a custom syntax-table property that cperl-mode puts on 
"1".

Clément.
