Datagrid deleteline vs deletelines issue

[zryip theSlug]

Henry,

I can confirm, the deleteLine behavior changed in dg2. Inside the dg2
library, deleteLine and deleteLines are different handlers now (deleteLine
is managing some animation now according to the comment I've seen in the
code). Inside dg1, deleteLine was just calling deleteLines.
Same remark with the deleteIndex and deleteIndexes command.

Inside DGH I've changed deleteLine for deleteLines for fixing a bug but I
did not read the documentation. This is probably something to update inside
the documentation with a warn about ascendant compatibility.
