bug#7103: Gnus thread indentation character customization

[Esa Peuha]

[-- Attachment #1.1: Type: text/plain, Size: 245 bytes --]

The %I specifier of gnus-summary-line-format always indents with spaces
without any way to use a different character. It would be possible to
indent with %B instead of %I, but is seems better to add a customizable
variable (see attached patch).

I don't think this would be generally all that useful -- if people want
more advanced threading displays, they're likely to want stuff like
|--->
+------->
and the like, so just adding a variable to tweak %I seems superfluous.
So I'm closing this bug report.

Well, I think that if people want to change the indentation, then just
substituting one character for another is probably not what most of
those people want.  They want arrows and lines and stuff.  Which they
can achieve with `gnus-tmp-level' and a user-format spec...
