This probably still fails with the "lua" command has a different version
than the library that Vim was built with. I hope someone can figure
out a better solution to get the patch level.

Yes. The Lua _VERSION global variable only contains the major and
minor version numbers. It doesn't have the patch version number.
When the lua command is invoked with the "-v" argument, then it
displays all the three version numbers. But if the lua executable is
not present in the PATH or some other version is found, then we may
get the wrong Lua version. I hope someone more familiar with Lua
can chime in with a solution to get the Lua version.

I suspect that the executable may be called something else, e.g.
"lua45".
