bug#73817: 29.4; Docstring for math-approx-sqrt-e is wrong

[Ulrich Mueller <ulm@gentoo.org>]

[-- Attachment #1: Type: text/plain, Size: 374 bytes --]

math-approx-sqrt-e is a variable defined in ‘calc-ext.el’.

Its value is (float 1648721270700128146849 -21)

An approximation for sqrt(3).

  This variable may be risky if used as a file-local variable.


Obviously this should be sqrt(e) = 1.648..., whereas sqrt(3) = 1.732...

OK to push attached patch to the emacs-30 branch, or should it go to
master?
