I'll replace above block to c_isspace().

BTW, I copied its block from virSkipSpaces().
It seems meaningful virSkipSpaces() treats backslash as space,
but I think backslash is not space generally.

Is it OK that virSkipSpaces() treats backslash as space?
Doesn't it need to rename something and define another virSkipSpaces()
which doesn't treat backslash as space?
