Problem: The generated sessions file does not restore tabs properly if :lcd
was used in one of them.
Solution: Create the tab pages before setting the directory. (Yee Cheng
Chin, closes#3152)
Problem: Loading a session file fails if 'winheight' is a big number.
Solution: Set 'minwinheight' to zero at first. Don't give an error when
setting 'minwinheight' while 'winheight' is a big number.
Fix using vertical splits. Fix setting 'minwinwidth'.
(closes#2970)
Problem: Terminal windows in a session are not properly restored.
Solution: Add "terminal" in 'sessionoptions'. When possible restore the
command running in a terminal.
Problem: Manual folds are lost when a session file has the same buffer in
two windows. (Jeansen)
Solution: Use ":edit" only once. (Christian Brabandt, closes#1958)
Problem: When creating a session when winminheight is 2 or larger and
loading that session gives an error.
Solution: Also set winminheight before setting winheight to 1. (Rafael
Bodill, neovim #5717)
