also the source code checks for "?" contained in the pattern and sets
"use_regexp=1", but this makes
only sense if then all "?" are converted to "." to match the documentation.
also when use_true_regexp is not set then a "*" must normally be
translated into ".*" otherwise the last
character of the "argument" is 0 or more times allowed, because
internally all patterns are computed
as regexp and not as globs as the documentation states.
But nevertheless i actually have converted my config to true regexps
