build tmux with debug symbols, ok claudio nicm
If no floating panes, reset default starting position, and reset if any part of the pane goes outside the window.
Empty string for invalid old-style formats causes old iTerm2 versions to crash, so emit "0000," instead.
Fix session_*_flag format variables which loop over the windows (they should only be false if all windows do not have the flag, not the first one). GitHub issue 5599.
Do not loop forever if someone tries to give WCHAR_MAX a width, GitHub issue 5602.
Expand -c for run-shell like the other -c flags, reported by Saúl Nogueras.
Reset layout manually instead of calling window_unzoom which can go down the notification path and end up double freeing the pane (this was previously removed in 2015 but added back to fix a problem with late destroy - this is a better fix). GitHub issue 5591 from Romain Francoise.
