[pacman-dev] [PATCH] Remove use of `seq` in pactree

[Dan McGee]

This is not a bash builtin, so can potentially cause portability issues.
Additionally, the use of it is completely unnecessary as it can all be done
within bash (and done faster).

$ time pactree xfwm4 >/dev/null (old version)
real	0m3.245s

$ time ./contrib/pactree xfwm4 >/dev/null (new version)
real	0m3.042s
