[ESS] polymode, tangentially related to ESS

[Vitalie Spinu]

Hi Everyone, 

The tabs/buffer ring repetition can probably be easily solved by giving
indirect buffers "invisible" names that start with a space. I didn't
bother with that so far because polymode is still in development (quite
frustratingly). The font change problem I don't quite follow. Aren't all
buffers suppose to use the same default font? Chris, could you please
post two screen-shots, so we can see the difference? If possible as a
new issue on github. Thanks.

There might be some fortification changes that come from overlays that
some modes use, like flyspell. Flyspell is taken care of in polymode,
there might be other minor modes that would need special
attention. Another problematic mode is "linum" which uses overlays for
each line in the buffer and cause noticeable slowdown.

I have been planning to come back to polymode for over a month now, but
it didn't happen as I am stuck over my head with one of the work related
projects. It completely eats even my weekends right now.

There are many more things to implement in polymode, most notably to add
weaving/exporting backends like sweave/knitr/pandoc/org-mode. I am
tracking all the discussions on this list and noting down all the
ideas. So please keep proposing/complaining either here or on github
development page. All of them will be eventually taken care of.

   Vitalie
