wxGUI file type option. File path corrupt if contained backslash

[naokiueda]

in wxGUI script, place 'File' type option to open file dialog.

Example:

"c:\aaa\bbb bbb.txt". OK. --> "c:\aaa\bbb bbb.txt"

"c:\aaa\bbbbbb.txt". NG. --> "c:aaabbbbbb.txt"

Work Around: Add "space" in front of/end of value.

" c:\aaa\bbb bbb.txt". OK. "c:\aaa\bbb bbb.txt"

"c:\aaa\bbb bbb.txt ". OK. "c:\aaa\bbb bbb.txt"

does the same happen in GRASS 7? (where msys troubles go away)
