By removing unnecessary preg_match and function calls - isCurrentLineEmpty() contains a call to isCurrentLineBlank() - therefore this function is called twice every time this condition is hit. The preg_match appears to legacy handling of blank lines.

This improves the performance of the Drupal 8 installer.
