[Po4a-devel][patch] Making Html.pm (slightly) better

Hi all, It looks like my spare time has shrunk further, hence my long silence. Martin's last comments, and my spending some time reading Sgml.pm and Xml.pm, along with running into harder files from my site, have me almost convinced that Martin is right and Html.pm is going the wrong way. Here is the patch to it that I currently use. This brings it to state in which it is useful for "simple" files (i.e. files with simple paragraphs, little in-line formatting), which I think still is useful for sites that contain a lot of simple text (how-to's, for example, would be good candidates if they used html as their primary format). It doesn't change the fundamentals of its working, so all of Martin's objections still hold true. Rather, it fixes the module's shortcomings: * Paragraphs are now spit along paragraphs, instead of random 512-byte-aligned boundaries, * title and alt attribute contents now create msgids. I hope to get some time to play with Sgml.pm and Xml.pm soon (because, let's face it, it's much more fun than actually doing translations). Y.
