I agree with the consistency issue, but not with using the first
way. makepkg is executed with `/bin/bash -e`[1].  Whenever
a command returns a non zero exit status makepkg exits
immediately.  See bash(1) or set(1p).  Thus conditional checks
on single commands with && and || are seldomly required[2].
Even in the second case the "update" step is never reached.

I personally find the second form easier to read, as one does
not have to think about why the && was mixed in, and if this
makes sense.
