Hi Ihor,
   Here is an updated patch. We can't use accept-process-output
because it doesn't seem to block in the way we need, or it blocks
exactly long enough for the process to finish but then continues
immediately to search instead of allowing the function that fills
the buffer to complete. Instead I use sleep-for a shorter time and
process-live-p which gives better results. I think I got the commit
message formats right this time. Best!
Tom
