The reason why replace-regexp-lax-whitespace is important to have
is not just for consistency but because replace-lax-whitespace
should not affect regexp replacements. But currently its value applies
to regexp replacements because it depends on calls from isearch that has
a separate variable for regexp that starts a lax-whitespace regexp replacement
to replace the same regexp matches as in isearch. So actually a lax-whitespace
regexp replacement feature exists in replace.el implicitly. A clean way to
fix this problem is to add a new option replace-regexp-lax-whitespace:
