Hi everyone!
I've found that executing an external programs via ruby binding is
somewhat broken (assuming Ruby version 1.9.2 or higher):
:ruby puts `pwd`
Error detected while processing command line:
NoMethodError: undefined method `flush' for #<Object:0x00000001d26f80>
Ruby binding redefines stdout object, but it seems that Ruby 1.9
assumes that IO objects implement 'flush' methods thus the above
error.
The following patch should fix it:
