--- Comment #13 from Josh Stone <jistone at redhat dot com> ---
ENABLE_PROLOGUES is not quite right.  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?
