bug#52329: Fix alignment of makefile-backslash-region

[Fredrik Bergroth]

Sure!

emacs -Q --eval '(makefile-mode)' --eval '(insert "a\nbbbbb\ncc")' --eval '(mark-whole-buffer)' --eval "(call-interactively 'makefile-backslash-region)"

This will end up with a bunch of tabs (rather than spaces) after the "a" and the b:s. If you now change tab-width to 2, the backslashes won't align.

Thanks for the patch.

Could you provide a recipe to reproduce this problem, preferably
starting from "emacs -Q"?
