[sork] vacation \U (full user name) not full

[dev at stean.ch]

hello all,

installed vacation h3-3.1, using the sql driver with custom queries.
the configuration help says that \U will be substituted with the
full user name, but it is not. for user1 at example.com i get user1.

had also installed forwards, with the same settings where i get
the full user name as expected, again with an sql backend.

do i missunderstand the configuration or is this an error in the
vacation module ?

regards, stephan
