[Weechat-dev] [bug #30602] display chokes on messages containing tab-characters

[Nicolai Lissner]

Follow-up Comment #1, bug #30602 (project weechat):

More info collected about this problem and how to reproduce it:

The additional chars appearing have their source in the line above, and this
is also the reason why it wasn't easy to reproduce in tests... as a test
channel doesn't scroll.
it needs scrolling to appear. Interesting enough, these letters "drop down"
not at the position of the tab itself, but the next non-tab whitespace (" " or
even n), so receiving

footbar
results in: foobar<LETTER AT 7th POSITION ONE LINE ABOVE>

foot bar 

so the problem should be found in the scrolling code, not the code that
prints the message.
