The former true/false values should now be always/auto to keep the same behavior -- there was no never. It appears you removed prologues from usage() entirely, instead of adding your new switch to the output. Why? The manpage explanation of "auto" is odd: "enable only if possible"? As if "always" will instead do the impossible? :) The real logic behind auto is a heuristic for when we think it will be useful, in userspace with low quality location info. Not sure of a short blurb -- maybe just "enabled by heuristic". The staprun.h change doesn't belong at all. I assume that was copying color_mode, but prologues are only a concern to the translator. Have you confirmed that --prologue-searching=never solves your original problem? -- You are receiving this mail because: You are the assignee for the bug.
