The default commit title when installing new packages is:

```committing changes in /etc made by "/usr/bin/bash"```

Instead of referencing the proper package manager process (pacman in my case)
This change fixes it:

```
--- a/etckeeper/post-install.d/50vcs-commit
+++ b/etckeeper/post-install.d/50vcs-commit
@@ -4,9 +4,7 @@ set -e
 pl="/var/cache/etckeeper/packagelist"
 
 # Parent process is etckeeper
-# (Only procps ps is currently supported, others will fail,
-# so this may end up empty.)
-ETCKEEPER_PID=$( ps --no-headers -o ppid "${PPID}" 2>/dev/null | sed 's/^ *//' )
+ETCKEEPER_PID=${PPID}
 
 # Find the parent of etckeeper and get the command line of the process
 if ! [ -z "${ETCKEEPER_PID}" ]; then
```

So that the commit title is now proper, eg.:

```committing changes in /etc made by "pacman -S minidlna"```

Will you include this fix?
Or is it expected that I open a pull request? Not sure how it's done on this site as I'm not familiar with it...
