When executing "drush mbdl" on a current 6.x-2.x-dev, the following error is emitted a few hundred times
WD php: Warning: preg_match(): Delimiter must not be alphanumeric or backslash in file_scan_directory() (line 1656 of [warning] /Applications/MAMP/htdocs/drupal-7.0-alpha3/includes/file.inc).
This is caused by a change in the meaning of $mask parameter to drupal_system_listing():
* in D6 drupal_system_listing() $mask was a ereg
* in D7 drupal_system_listing() $mask is now a preg_match

Fixed by putting a wrapper for this in common_version.inc.
