Subject: 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.

Hello Michel,

Thanks for the report. Maybe this patch will help?

I've done some very limited testing, by manually changing the code on
my version of calc according to your patch, and it seems to do the
trick indeed!

Thanks again (and thanks for fixing the other calc bug I reported last
summer [about Julian days], I went on holidays just after reporting and
completely forgot to reply, sorry).

Michel.

Excellent! Pushed; the fix will be in the soon-to-be-released Emacs 27.1.

The pleasure was all mine --- not every day I get to mess with calendar intricacies.
