this inserts a space after lineno, but not otherwize.

I have patch to fix it, but maybe you want to fix it it here ?

If it doesnt apply, or you defer, I'll resend once Greg's accepted

Subject: [PATCH 03/28] dynamic_debug: add space at end of non-null
dynamic-prefix

dynamic_emit_prefix() currently adds a space after line-number,
but not otherwize. For readability, add space whenever any prefix
(besides the "<7>" loglevel) has been written.
