patch 8.1.0046: loading a session file fails if 'winheight' is big commit https://github.com/vim/vim/commit/1c3c10492a291270fa89b3c8df11828792f927d3 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Jun 12 16:49:30 2018 +0200 patch 8.1.0046: loading a session file fails if 'winheight' is big 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)

" This test is in a separate file, because it usually causes reports for memory
" leaks under valgrind.  That is because when fork/exec fails memory is not
" freed.  Since the process exists right away it's not a real leak.
