[git commit] echo: make escape sequences depend on fancy mode

Currently when you disable fancy echo, escape sequences are hardcoded
enabled (e.g. as if you used `echo -e` all the time). The opposite
behavior is more desirable (always disable -e support) because:
* This seems to contradict the spirit of the kconfig help text (where
it says enable support for -n/-e flags), although you could say that
we aren't supporting the -e flag directly as `echo -e` will show the
* POSIX makes escape sequences optional, and even says they are there
only on XSI-conformant systems.
* It saves space (~100 bytes on x86_64).
* It makes things faster!
* It makes it behave more like bash where you need an explicit -e flag
in order for escape sequences to be interpreted.
