This considers globs as valid even if they return no matches when they have a prefix (and when that prefix exists, according to $ignoreErrors).
This means there is an edge-case:
*.abc with at least one match is OK, but when it has no match, it falls back to regular import, then usually will fil.
But rewriting this to ./*.abc resolves the ambiguity and turns this into a glob that won't fail if no matches are found.

This should provide the expected behavior in most cases (but ambiguous described one of course).

How would this look like for $loader->load($confDir.'/container'.self::CONFIG_EXTS, 'glob'); ?
Would the path be something like $configDir.'/./*.xml'?

This considers globs as valid even if they return no matches when they have a prefix (and when that prefix exists, according to `$ignoreErrors`).
This means there is an edge-case:
`*.abc` with at least one match is OK, but when it has no match, it falls back to regular import, then usually will fil.
But rewriting this to `./*.abc` resolves the ambiguity and turns this into a glob that won't fail if no matches are found.

This should provide the expected behavior in most cases (but ambiguous described one of course).

@nicolas-grekas Thanks, this definitely makes more sense for Flex-based apps (using glob patterns). 👍
