You can actually get it to work in bash 3.2, by writing:

if [[ $DOG =~ ([[:alpha:][:blank:]]*)-\ ([[:digit:]]*)\ -\ (.*)$ ]]
then
  echo Unquoted Dog ${BASH_REMATCH[2]} is ${BASH_REMATCH[3]}
fi

however this fails in 3.1 - it'll work in 3.1 if you also escape the
brackets, but that then fails in 3.2.  Which means the only way to
guarantee it is to write both, and check the bash version :/


Chet,
any comment on this issue? (see also my earlier mail from Sunday 14th,
http://lists.gnu.org/archive/html/bug-bash/2007-01/msg00035.html, and
Tim's bug at
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=220087)
At least to confirm/deny that it may be a real problem?


Thanks,
