Variable: mode-line-position-column-line-format
mode-line-position-column-line-format is a customizable variable
defined in bindings.el.gz.
Value
(" (%l,%c)")
Documentation
Format used to display combined line/column numbers in the mode line.
This is used when column-number-mode(var)/column-number-mode(fun) and line-number-mode(var)/line-number-mode(fun) are
switched on. The "%c" format spec will be replaced by the
column number, which is zero-based if
column-number-indicator-zero-based is non-nil, and one-based if
column-number-indicator-zero-based is nil.
This variable was added, or its default value changed, in Emacs 28.1.
Probably introduced at or before Emacs version 28.1.
