Fix calculator-string-to-number yet again (bug#47694)
* lisp/calculator.el (calculator-string-to-number):
The last bugfix changed the code to just blindly replace ".e". This
has some minor problems like making "-." parse as 0.0 instead of -0.0,
and ".1.e1" is parsed as 1 instead of 0.1. Instead, replace the first
"." that is followed by a non-digit with ".0". Since this has had
several problems over the years, add some tests too. (Also, restore
the original if-indentation style.)
