Package: tar
Version: 1.23-2.1
GNU tar exits with error when trying to process the filename
'\fhd =' (without quotes)
For instance, the command
tar vzcf file.tar.gz '\fhd ='
exits with the following error:
tar: \fhd =: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors
But the file actually exists; the command
stat '\fhd ='
returns
File: `\\fhd ='
Size: 0 Blocks: 0 IO Block: 4096 regular empty file

However, when the backslash of the weird filename is escaped, tar works as
expected:
tar vzcf file.tar.gz '\\fhd ='
\\fhd =
Since other utilities (like stat, ls, and so on) work promptly with '\fhd =',
I don't think that an additional backslash should be necessary. Moreover, the
tar's behavior precludes it from being used this way:
tar vzcf file.tar.gz *
(the above command exits with error if the weird filename is in the current
directory)
PS: The reported problem was observed on the following shells: bash (4.1.5),
zsh (4.3.10), and dash (0.5.5.1). I'm using Debian GNU/Linux unstable.
