OK, I've changed the keymaps for normal state in evil-mode to `man'(aha,
I didn't even notice that I could do this!)

There is another problem: when using `man', it would firstly catch the
symbol/word at point by default. When there is NO manpage for this
symbol, it still displays as a candidate(I am using ido-ubiquitous and
don't know the behavior in other cases). And when I hit RET, it would
report like this:

error in process sentinel: user-error: Can't find the time_t manpage

This is annoying. But `woman' would ignore the symbol where the cursor
locates(it would not display `time_t' in this case) and I am informed
ahead that I cannot get the manpage of this symbol.

Also, the matching rule is confusing(possibly only for ido), for
instance, when I run `M-x man RET git', `git' does not appear at the
front of all candidates until I additionally add `(1)' (hence I have to
type the whole word `git(1)'), which is a bit inconvenient.
