Auto-indent selection has problems with digit separators

Using digit separators and then running auto-indent selection causes the next line to be incorrectly indented.  See example main.cpp, select all text, right-click and press auto-indent selection.  The output is shown in file main_after_auto_indent.cpp.

Before:

int32_t var = 1'000;

std::cout << "var: " << var << std::endl; 

After:

int32_t var = 1'000;

            std::cout << "var: " << var << std::endl;
