# Errors and warnings that also show on the display (M117: the status line in
# Mainsail and KlipperScreen, display_status.message)
#
# action_raise_error aborts while the macro is rendered, before any of its
# G-code runs, so an M117 in the same macro never shows. _ERROR sends the
# M117 first and raises the error in a separate macro: the display keeps the
# text and the calling macros are aborted as with action_raise_error.
#
#   _ERROR MSG="full text for the console" DISPLAY="short text"
#   _WARN  MSG="full text for the console" DISPLAY="short text"
#
# DISPLAY defaults to MSG. No double quotes in either (they end the
# parameter). Nothing after an _ERROR in the calling macro runs, but
# anything that macro does while rendering (action_respond_info, ...) has
# already happened: put the rest in an else branch.
