commit 6427bef6d182b98dce746467c7c09e19e7cf7e2d
Author: Yao Qi <yao@codesourcery.com>

    Don't replace '\' with '\\' in before_prompt_hook
    
    In gdb/command/prompt.py:before_prompt_hook, the '\' in the new prompt
    is replaced with '\\', shown as below,
    
    >     def before_prompt_hook(self, current):
    >         if self.value is not '':
    >             newprompt = gdb.prompt.substitute_prompt(self.value)
    >             return newprompt.replace('\\', '\\\\')
    >         else:
    >             return None
    
    I don't see any explanations on this in comments nor email.  As doc
    said, "set extended-prompt \w" substitute the current working
    directory, but it prints something different from what pwd or
    os.getcwdu() prints on mingw32 host.
    
    (gdb) python print os.getcwdu()^M
    \\build2-lucid-cs\yqi\yqi\arm-none-eabi
    
    (gdb) pwd^M
    Working directory \\build2-lucid-cs\yqi\yqi\arm-none-eabi
    
    (gdb) set extended-prompt \w
    \\\\build2-lucid-cs\\yqi\\yqi\\arm-none-eabi
    
    This makes me think whether the substitution in before_prompt_hook is
    necessary or not.  This patch is to remove this substitution.
    
    Run gdb.python on x86_64-linux and arm-none-eabi on mingw32 host.  No
    regressions.

    	replace '\\' with '\\\\'.
