extglob and dots

[Benoît VILA]

hi

i made a bug repport few days ago but i'm not sure it reached the list, 
anyway my concern is quite simple, i got a pattern which doesn't match 
what he should do : +([[:alpha:].]) which doesn't match strings composed 
of letters and/or dots, it just match letters-only-composed string 
whereas *+([.])* works fine to match strings contenning dots and only 
strings with at lesat one dot so just wondering if it is fixed or known 
or even a normal behaviour...

thanks for answering

it was tested (among athers) on a debian with bash 3.1-5(release)
