Re: PATCH

[Abhijit Halder <abhijit.k.halder@gmail.com>]

How if we just put a condition check whether the entered string after
pipe (|) is numeric. For e.g.
(gdb) thread apply all bt | grep foobar
Here the entered string after | is grep foobar which is not numeric.
But here (gdb) print var | 0x50 is numeric.

We may safely use this above notion as in case of any numeric file
name can be encapsulated within quote.

Soon I will submit the updated patch. Please provide feedback on this.
