Taking embedded spaces out of existing prefixes makes them more easily searchable; simplifying the extra quoting needed otherwise: $> echo format "^gvt: core:" +p >control Dropping the internal spaces means any trailing space in a query will more clearly terminate the prefix being searched for. Consider a generic drm-debug example: # turn off ATOMIC reports echo format "^drm:atomic: " -p > control # turn off all ATOMIC:* reports, including any sub-categories echo format "^drm:atomic:" -p > control # turn on ATOMIC:FAIL: reports echo format "^drm:atomic:fail: " +p > control Removing embedded spaces in the format prefixes simplifies the corresponding match string. This means that "quoted" match-prefixes are only needed when the trailing space is desired, in order to exclude explicitly sub-categorized pr-debugs; in this example, "drm:atomic:fail:".
