[PATCH 0/1] MR1184: user32: Fix rounding issue in edit tests for char pos messages.

[eric pouech (＠epo)]

- the tests were failing in Hindi/UTF8
- rounding with (lo+(hi-lo+1)/2) let all the tests pass
- rounding with (lo+(hi-lo)/2 + 1) (as it's done when
  ES_MULTILINE is enabled) let the Hindi/UTF8 fail
- it looked weird to have different rounding computation
  in single vs multi line
- so, changing all rounding to (lo+(hi-lo+1)/2) let all
  the tests pass
