[Dillo-dev] Fun with autocnf and mercurial

Here's a patch for discussion. Since I am parsing Dillo logs for debugging, I thought it would be neat if Dillo logged the mercurial revision. Patch attached. Thoughts? Does anyone know a better way to get the revision for a particular tag? Piping "hg tags" through a sed script is rather kludgy but I can't find a way to get mercurial to tell me directly. I log the qparent revision as well as the tip revision because I manage patches with Mercurial queues, so my qparent revision is the vanilla tip revision that I am currently based on. Also, I used printf() to log the revisions because neither MSG nor MSG_WARN produced anything. I don't know why. Can anyone explain? Regards, Jeremy Henty
