bedtools 2.30.0 intersect with 0-length intervals

[ddrichel]

bedtools intersect (v.2.30.0) seems to not handle 0-length intervals correctly. Example for length 1 and 2:

$ cat a.bed 1 1 10000 cat b1.bed 1 5 6 $ bedtools2/bin/bedtools intersect -a a.bed -b b1.bed 1 5 6 $ cat b2.bed 1 4 6 $ bedtools2/bin/bedtools intersect -a a.bed -b b2.bed 1 4 6

So far, makes sense. But for length 0:

$ cat b0.bed 1 5 5 $ bedtools2/bin/bedtools intersect -a a.bed -b b0.bed 1 4 6

Expected output is: 1 5 5

Kind regards
