[PATCH v2 3/3] perf hists browser: Reset selection when refresh

2015-12-02 Thread Wang Nan
With following steps:

 Step 1: perf report

 Step 2: Use UP/DOWN to select an entry, don't press 'ENTER'

 Step 3: Use '/' to filter symbols, use a filter which returns
 empty result

 Step 4: Press 'ENTER'

We see that, even if we have filter all symbols (and the main interface
is empty), pressing 'ENTER' still select one symbol. This behavior
surprise user. This patch resets browser->{he_,}selection in
hist_browser__refresh() and let it choose default selection. In this
case browser->{he_,}selection keeps NULL so user won't see annotation item
in menu.
