Comment (by felixs):

 Every hack should be removed. Expecially the ones that implement things
 that can be achieved easily without hacks.

 Hacks are often misleading and complicate issues. Getting rid of them
 needs more work, but this ticket is meant to just handle this particular
 case, I came across.

 The whole story is: a doctest checks the first line in
 `$SAGE_LOCAL/bin/ipython`. This doctest will certainly fail, if ipython
 has been disabled (toplevel build system, #14796). That's why #14796,
 depends on #15105 (unhardwire paths). In the `ipython` case, unhardwiring
 paths can be simply achieved by removing the doctest. With this ticket,
 there is no doubt about how the first line in `ipython` looks like (in
 case it came from sage) and the doctest is unnecessary.
