waf uses an inline tar file extracted by the tarfile module. The tarfile module may print a warning when used with default 'filter' argument[0]. When called to get the version, the first time after unpack, the output may look like: # output from lower modules (e.g: warnings from tarfile, ...) waf X.Y.Z ... This patch makes the version parsing more precise by looking at the first line matching "waf ".
