Bug: 0 is not considered a valid number for {num1..num2}

[uap-universe]

editorconfig-core-c/src/lib/ec_glob.c

Lines 377 to 379 in c32b33d

	/* we don't consider 0digits such as 010 as matched */
	if (*substring_start == '0')
	break;

This does not only discard numbers like "010", but also the "0" itself.

That means, the following pattern

*.orig.{0..9}

does not match the file

data.txt.orig.0

You're looking at a specific implementation here, I sort of agree that the above pattern should be part of the test suite: https://github.com/editorconfig/editorconfig-core-test/blob/master/glob/braces.in#L65-L67

Indeed, the spec says

{num1..num2}

any integer numbers between num1 and num2, where num1 and num2 can be either positive or negative

which would imply zero should be allowed.

I am closing this in favor of the spec issue at editorconfig/editorconfig#371 . Once that issue is resolved, we will update the core tests and the cores will all need to be updated accordingly.
