- docs: mention --luadev-mod to run with lua runtime files
  When changing a lua file in the ./runtime folder, a new contributor
  might expect changes to be applied to the built Neovim binary.

Problem:
When "-l" is followed by "--", we stop sending args to the Lua script
and treat "--" in the usual way. This was for flexibility but didn't
have a strong use-case, and has these problems:
- prevents Lua "-l" scripts from handling "--" in their own way.
- complicates the startup logic (must call nlua_init before command_line_scan)

Solution:
Don't treat "--" specially if it follows "-l".

update man file to match

Problem:
man/ contains source files for manpage generation, it doesn't need to
live at the project root.

Solution:
Move it to src/man/.
