Describe your question, feature request, or bug.

Ripgrep does not match the string abc;de,fg with the regex ;(.*,){1}.

If this is a bug, what are the steps to reproduce the behavior?

This returns no lines:

echo 'abc;de,fg' > foo.txt
rg ';(.*,){1}' foo.txt

If I remove the {1} repetition on the group, I do get a match:

echo 'abc;de,fg' > foo.txt
rg ';(.*,)' foo.txt

I also get a match with PCRE:

echo 'abc;de,fg' > foo.txt
rg -P ';(.*,){1}' foo.txt

If this is a bug, what is the expected behavior?

I expect the first example to return a match.

I know this is almost certainly due to my misunderstanding Ripgrep's regex syntax, but I've been racking my brain and I can't figure out what I'm doing wrong.
