If I create a ticket - and one of the committers closes it - and then I find the problem is not fixed - how do I re-open it? Is entering an additional comment enough to flag it as open again - or do I need to raise a new issue?

E.g. 2322: Cannot type ' (apostrophe) next to an existing character - was marked closed - however the issues was not correctly fixed by the proposed filein (it introduces other related problems).
