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

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. -- Happy hacking, ~ Luke Shumaker
