I can not get Cream 0.39 to replace <spaces> with <Tabs>.
If I put <Tabs> in the file using the tab key, Cream will find them.
If I try to replace a <space> with a <Tab> use the Cntl-H shortcut and put "\t" (without the quotes) in the replace window, Cream put the literal \t in the file.
I have modified my _vimrc to include a line that says "set magic". This did not help.
