Use `:wall` instead of `:bufdo update`

[sol]

@907th I know that you don't maintain this plug-in anymore, but do you still remember, by any chance, if there's an important reason to use :bufdo update instead of simply :wall?

:wall

• Writes all files that have been changed.
• Includes hidden buffers, non-listed buffers, and even those not currently visible in a window, as long as they are loaded and modified.
• Can trigger error messages or prompts for things like:
  • Read-only files.
  • Buffers with unsaved changes that can't be written due to permissions.
  • Might be too aggressive in an auto-save context.

:bufdo update

• Runs :update on each listed buffer (those shown in :ls) one by one.
• :update only writes the file if it has been modified.
• Skips unmodified buffers silently (avoids unnecessary writes).
• Respects hidden and buftype options more gently.
• Less likely to interfere with buffers that are:
  • Open from netrw or plugins.
  • Read-only or non-file buffers.
