New behaviour with --output= option ?!

[Luc]

new  behaviour with version 2.11.44 (windows xp)

IIRC, when invoking lilypond, the option --output=folder directed all output 
files to the specific folder.

Now this has changed: If I run "lilypond --output=myOutput C:\myFile.ly" and 
there is no folder called "myOutput" I get 2 files: 

myOutput.pdf and myOutput.ps in the folder where lilypond was running,

but if a folder exists with the name "myOutput" I get 2 files:

\myOutput\myFile.pdf and \myOutput\myFile.ps in that folder

what's the logic or intention?

thx
