bug#51260: 29.0.50; smerge-mode: void-variable smerge

[Manuel Uberti via "Bug reports for GNU Emacs, the Swiss army knife of text editors" <bug-gnu-emacs@gnu.org>]

Hi,

if I do the following:

- emacs -Q
- M-x toggle-debug-on-error
- M-x smerge-mode

I now get:

Debugger entered--Lisp error: (void-variable smerge)
