Your changes in ibuffer.el and ibuf-ext.el

[Eli Zaretskii]

Those changes seem to trigger compilation warnings:

    ELC      ibuffer.elc

  In toplevel form:
  ibuffer.el:1333:1:Warning: argument `_mark' not left unused

  In toplevel form:
  ibuf-ext.el:1504:1:Warning: Unused lexical variable `char'
  ibuf-ext.el:1504:1:Warning: variable `_buffer' not left unused

Those sound like actual problems that need to be fixed.  (Did you know
about the special meaning of the leading underscore in argument
names?)

Thanks.
