Yes, escape was same as replace, my bad.

This is still achievable by use of replace followed by wrap(the way they
are).
Something that you mentioned in the first reply (don't wrap if the fragment
is already present) is still not possible.
That is what I was trying to solve for with ignore-boolean.
Eg.
wrap("foo", "_", true) => "_foo_"
wrap("_foo", "_", true) => "__foo_"
wrap("_foo", "_", false) => "_foo_"
The third param here is the ignore_if_already_present boolean.
