Subject: bug#39040: 26.3; calc: interval forms entry not working with single digits
Date: Wed, 08 Jan 2020 16:09:35 +0100

Recipe:
- start Emacs (with -Q),
- launch Calc (M-x calc RET),
- type an opening parenthesis, to start an interval form,
- type the digit 1,
- type the dot twice (..) to indicate an interval form (see §4.12 and
  §4.13 of the Calc manual),
- notice that the (incomplete) interval form at the top of stack is
  incorrect: it is "(-inf .. ..." instead of "(1 .. ..." as it should be.

Notice that this problem only appears if a single digit (0 to 9) is
entered as the beginning of the interval form. All other values,
including -0 (negative zero), seem to work correctly. Also, using "M-x
calc-dots" instead of typing two consecutive dots works correctly.
