[arch-projects] [devtools] Help text editors out a bit

[Luke Shumaker]

This pair of patches helps text editor programs when editing the
files.

For non-executable bash files, a phony shebang "#!/hint/bash" provides
a hint to text editors that the shell dialect for that file is Bash;
and is general that basically every text editor will understand it,
unlike most other editor hints; without misleading a user into
thinking that maybe the file is executable, like "#!/bin/bash" would.

`commitpkg` had a line with a bunch of complex quoting and
backslashes; it was confusing Emacs, and caused the rest of the file
to be a string, wcrwing up syntax highlighting, but more importantly,
auto-indentation.
