Summary: regedit gives false Unrecognized escape sequence errors
                    when importing from a .reg file
           Product: Wine
           Version: 0.9.7.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: critical

I am trying to import some registry keys that were exported in ASCII format from
a Win2000 machine.  When importing via regedit (invoked wine regedit), it
returns errors on any entries that include a backslash ("").

For the follwing registry key:

REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes.blk\ShellNew]
"Filename"="c:\program files\test_me\this_is_a_test.txt"

I get the following errors:

Warning! Unrecognized escape sequence: \p'
Warning! Unrecognized escape sequence: \t'
Warning! Unrecognized escape sequence: \t'

I think the error is in the "REGPROC_unescape_string" routine in regproc.c .
