Problem: :exe command line completion only works for first argument. Solution: Skip over text if more is following. (closes vim/vim#7546)4941b5effdPort "IS_WHITE_OR_NUL" macro from patch v8.2.0562 as "ascii_iswhite_or_nul()" inline function. N/A patches for version.c: vim-patch:8.2.0782: cannot build with Lua on MS-Windows Problem: Cannot build with Lua on MS-Windows. Solution: Add DLL symbol for luaL_Loadstring. (Ken Takata)df1643a6a7vim-patch:8.2.0856: CTRL-S stops output Problem: CTRL-S stops output. Solution: Invert the IXON flag. (closes vim/vim#6166)928eec649bvim-patch:8.2.1212: cannot build with Lua 5.4 Problem: Cannot build with Lua 5.4. Solution: Use luaL_typeerror instead defining it. (closes vim/vim#6454)5551b131davim-patch:8.2.2211: MS-Windows: can't load Python dll if not in the path Problem: MS-Windows: can't load Python dll if not in the path.
