Disable smooth day and night transition in the config file not working

The example configuration file on the Redshift website reads:

; Enable/Disable a smooth transition between day and night ; 0 will cause a direct change from day to night screen temperature. ; 1 will gradually increase or decrease the screen temperature. transition=1

There seems to be a bug in Redshift that causes the transition option in the configuration file to not work as described: Instead of handling the transition between day and night it only changes the transition between application start-up and shutdown (and delay the latter as a consequence). So transition=0 does not cause a direct change from day to night screen temperature.

This issue was observed on Gentoo and Arch Linux with the latest Redshift release.

Many thanks for this great program!
