Support formatting

I made a custom bash script that do a sort of scrolling, and I’m trying to replace it by your program (because of some limitations, like fullwidth characters). But I got another problem, my custom script was able to manage formatting. In case of MPD, the artist name was bold, so the output look like this (for a 10-wide scrolling): ``` <b>Eric Prydz</b> <b>ric Prydz</b> <b>ic Prydz</b> P <b>c Prydz</b> Pj <b> Prydz</b> Pja <b>Prydz</b> Pjan <b>rydz</b> Pjano <b>ydz</b> Pjanoo <b>dz</b> Pjanoo <b>z</b> Pjanoo ( Pjanoo (C Pjanoo (Cl janoo (Clu anoo (Club […] ``` So the `<b></b>` weren’t counted in the total length, and removed when not necessary. I have no idea on how something similar can be implemented in you program (and generic, not only `<>` tags). It’s probably easy to ignore a substring in the count, but it’s harder to decide when adding or removing tags from the final string… but I think it can be a really cool enhancement. (The way I’m doing it in Bash is… terrible.)

Where are you printing text that supports formatting? Is this some panel? It would potentially be possible to support a specific format by changing the `visual_len` and `make_visual_len`, but I can't think of a way to support generic formatting... Maybe a regexp to strip out formatting (if a regexp is good enough to handle the formatting)?
