I would prefer flag with the following result:

pattern.startswith("*") => match any name except one starting with '.'
  (i.e. set GLOB_PERIOD implicitly)
pattern.startswith("**") => match any name except "." and ".."
  (i.e. set GLOB_HIDE_DOTDIRS implicitly)
pattern.startswith("***") => match any name
pattern.startswith(".*") => match any name starting with '.' except "." and ".."
  (i.e. set GLOB_HIDE_DOTDIRS implicitly)
pattern.startswith(".**") => match any name starting with '.'

 ... and make it default for /bin/sh except Posix compatible mode is requested.

(of course, its result shall be limited according to tail of the pattern)

In this way we will cure innate patology of glob matching.
