Problem: Crash when going through spell suggestions.
Solution: Limit the text length for finding suggestions to the original
length. Do not update buffers when exiting. (closes#8965)
Problem: When 'clipboard' is "unnamed" zp and zP do not work correctly.
Solution: Pass -1 to str_to_reg() and fix computing the character width
instead of using the byte length. (Christian Brabandt,
closes#8301, closes#8317)
Problem: Getting the selection may trigger TextYankPost autocmd.
Solution: Only trigger the autocommand when yanking in Vim, not for getting
the selection. (closes#7367)
Problem: When using :global clipboard isn't set correctly.
Solution: Set "clip_unnamed_saved" instead of "clip_unnamed". (Christian
Brabandt, closes#6203, closes#6198)
