COLUMNS incorrect for the first prompt in a session #4141
fish, version 2.6.0
With a fish_prompt of
function fish_prompt echo "$COLUMNS > " end
I see some weird behaviour. Specifically, the first prompt of any fish invocation prints 80, while subsequent prompts print 120 (actual width).
This happens for new tabs, new windows, and even nested fish shell invocations.
Pressing return, resizing the window (in either dimension), pasting something (presumably because of the syntax highlighting), or even pkill -SIGWINCH fish in another session, all fix the prompt.
I have a "-d 3" log of fish, where all I do is press return to update columns and then quit.
