I can only guess because this code was added when the function was
introduced in commit 65962685 (ui-refs.c: show download links for all
tags referring to commit objects, 2008-12-01). I think it is related to
the code below accessing ref[1], though. I don't see how anything could
go wrong when the string length is 1 since isdigit('\0') should return
0 in that case. +1 from me.
