PuTTY wish do-text-splitting

This is a mirror. The primary PuTTY web site can be found here.

summary: Frontends need control over where do_paint() splits runs
class: wish: This is a request for an enhancement.
difficulty: tricky: Needs many tuits.
priority: medium: This should be fixed one day.

Currently, the way that do_paint() decides where to split the text runs it passes to do_text() is rather ad hoc and messy. It splits whenever there is a change to the "attributes" of the characters (subject to term->attr_mask), which includes any changes to the high-order byte of the character codes. It also splits around characters in the U+23BA–U+23BD range because the Windows front-end needs this.

It seems to me (BJH) that we could do with some way for the front end to inform the run-splitting code, so that do_paint() could put in splits where the front end needs them, and not put in spurious splits where it doesn't. I don't yet have any clear idea how this should work, though.

Audit trail for this wish.
