From: Dave Reisner
converts a pacman log file to a list of installed packages, which should
match the output of `pacman -Q'.
This isn't bullet proof, as testing has revealed that the log is not always
precisely accurate, but it should be good enough for a user whom finds
himself in a situation dire enough to need this.

The bracket in the regular expression in line 42 needs to be escaped, otherwise
OpenBSD's awk(1) fails with:
----
awk: illegal primary in regular expression ) at
source line number 42 source file log2pkglist
context is
sub(/)/, "", >>> upgver) <<<
----
Apart from that, this works fine for me (OpenBSD 4.9, awk version 20100523).
