Problem with using backslash to quote spaces in "--prunpaths"

[Linda A. Walsh]

Backslash doesn't seem to work correctly when quoting a space in the
--prunepaths option. 

Backslash does properly quote a dollar sign, but if you enable the
trace in updatedb, you'll see that it does something weird w/space, and
instead adds a backslash before a quote, and still splits the filename.

An awkward workaround is to use [[:space:]], so it's not a show-stopper,
but it's certainly not intuitive to people use to using backslash
to quote characters in filenames and regex's...

Should I just file a bug on it?

Thanks!
