commit 72e332c986304775e91020c88ded1ba9d7226023

Ibuffer filter by modes: Accept several mode names
Extend all mode filters so that they handle >1 mode.
For instance, if the user wants to filter all buffers in
C or C++ mode, then s?he can call the filter interactively
with input: 'c-mode,c++-mode' (Bug#32731).
* lisp/ibuf-macs.el(define-ibuffer-filter): Add key :accept-list.
If the value of this key is non-nil, then the filter accepts
either a single qualifier or a list of them; in the latter case,
the resultant filter is the `or' composition of the individual ones.
* lisp/ibuf-ext.el (ibuffer-filter-by-used-mode)
(ibuffer-filter-by-mode, ibuffer-filter-by-derived-mode)
Set :accept-list value non-nil.
Interactively, accept a comma separated list of mode names.
* etc/NEWS(Ibuffer): Announce this change.
