wgrep doesn't work in ivy-occur-grep-mode if the original line contains tabs

[binshengliu]

Sample file:

\tabc

Steps:

1. Call swiper
2. Type abc
3. Call ivy-occur
4. Call ivy-wgrep-change-to-wgrep-mode
5. Make some modification to the line
6. Call wgrep-finish-edit

Result:

The modification is not applied to the buffer.

I looked into the code and found in swiper--line, tabs are replaced with whitespaces. wgrep would complain "Buffer was changed after grep." in wgrep-apply-change.

I tried to remove the tab replacing code and wgrep works.

Is this a problem, or do I miss something?
