We can now do this since we finally switched to PHP 5.3 for MW 1.20 and get rid of the silly dirname(__FILE__) stuff :)

checkSyntax.php now uses git commands to retrieve a list of modified
files instead of the svn command-line client.
The script now considers any files that have been changed since
the nearest common ancestor to the master branch to be "modified",
as it is probably desirable to include files modified in previous
commits on the same local topic branch that have not yet made it
into master.

Until now, we relied on setting MW_NO_SETUP which was a) hacky, b) irreversable, and c) likely to be forgotten if you didn't use one of the wrappers like runChild().
Instead, move the freaky magic to doMaintenance and have *it* check if it's in a specific call stack that indicates this is being run from the file scope and should be executed. Rename DO_MAINTENANCE to RUN_MAINTENANCE_IF_MAIN so it's nice and clear what magic happens behind the require_once().
