Set a Drupal's Webform paths automatically based on title. Add as custom module or to an existing module of your own.

/**

 *
 * Set a Drupal's Webform paths automatically based on the title. This improves
 * the default use of the machine name (32 chars max) which can result in
 * cropped or enumerated form URLs if the title is too long.
 *
 * The paths are set on the presave hook and will only be generated if the
 * fields are empty. Allowing for easy customization.
