lib/sh/util.sh: $log_level_indent: changed to a single space rather than two, to avoid very deep indents as the call tree becomes more deeply nested. due to the + at the beginning of every line, a single space is enough to visualize the structure of the call tree (unlike source code, which requires more whitespace because it doesn't have a call tree structure).
