Autocomplete incorrect match highlighting when displaying caption

[shds86]

I have some problem with autocomplite popup. In our suggestions we have length more than 32 symbols. But the Bitwise Left shift,

ace/lib/ace/autocomplete/popup.js

Line 188 in 4a55188

flag = data.matchMask & (1 << i) ? 1 : 0;

, is limited:

• 1 << 30 has result 1073741824
• 1 << 31 has result -2147483648

because bitwise operators treat their operands as a sequence of 32 bits,
therefore in next iterations we will have correct expression "data.matchMask & (1 << i)"
