Merge branch 'jc/apply-ws-fix-tab-in-indent'
"git apply --whitespace=fix" was not prepared to see a line getting
longer after fixing whitespaces (e.g. tab-in-indent aka Python).
* jc/apply-ws-fix-tab-in-indent:
test: resurrect q_to_tab
apply --whitespace=fix: avoid running over the postimage buffer
