bug#44488: Koutline: export to HTML, replace-regexp-in-string: Invalid use of ‘\’ in replacement text

[Jean Louis]

Before I could export, now I cannot with emacs -Q:

After asking me for the Koutline file, and export file name and title,
after pressing RET I get:

replace-regexp-in-string: Invalid use of ‘\’ in replacement text

Debugger entered--Lisp error: (error "Invalid use of ‘\\’ in replacement text")
