Unable to generate shift-only keywalks

[alexeypetrenko]

It doesn't seem to be possible to generate all-caps keywalks.

Here is an example:

caps.base:

QAZ

6.route:

6

en.keymap is original file

---

 $ kwp caps.base en.keymap 6.route

Output is empty, as expected.

---

$ kwp caps.base en.keymap 6.route  -s1
Qwertyu
Asdfghj
Zxcvbnm
QWERTYU
ASDFGHJ
ZXCVBNM

---

$ kwp caps.base en.keymap 6.route  -s1 -b0

Output is empty again. It would be nice to see following output here

QWERTYU
ASDFGHJ
ZXCVBNM

---

I'm using precompiled kwp release 1.00
