Subject: ui-shared.c: fix segfault when repo is empty
X-Git-Url: https://gitweb.ps.run/ps-cgit/commitdiff_plain/8d946079c5f51ce934ff5edf6333962c6061d8a5?hp=8d946079c5f51ce934ff5edf6333962c6061d8a5

ui-shared.c: fix segfault when repo is empty

PATH_INFO="/$REPONAME/commit/?id=1" QUERY_STRING="id=1" ./cgit.cgi
triggers segfault when the repository is empty and therefore
ctx.qry.head is unset
