[Sigbjorn Finne]

Hi,

thanks for the report. The upcoming release fixes this
usability issue, treating "\ " as " " in filenames (only.)

> In OS X, pathnames have two distinct syntaxes. The GUI uses the pre-X
> syntax, in which a pathname begins with a volume name and the
> separator is `:', as in

> Macintosh HD:Users:ham:Documents:whatever.hs
>
> In the Darwin (i.e., unix) command-line "underworld", a pathname
> begins with /Volumes, spaces are escaped with `\', and the separator
> is `/', as in
>
> /Volumes/Macintosh\ HD/Users/ham/Documents/whatever.hs

> When you drag a file icon onto the command line, Terminal does the
> right thing-- it converts the pathname from the GUI syntax to the
> Darwin syntax, and utilities such as more work just as they should.
