Dev:Coding Style

After a quick discussion on coding styles, here's what we've currently got for consensus:

shell scripts
if [ .. ] && [ .. ] || [ .. ] form, as opposed to [ .. -a .. -o .. ] form.
 * Shell scripts should be fully posix compliant.
 * We will favour the use of if [ ]; then else fi, over && and ||, for clarity
 * When using a multi check if, exception will be using the
 * If a single line test is used, use test &&/|| result, and only for tests that fit on a single line.
 * We'll use spaces instead of tabs, and the indentation level will be 4 spaces, the same as python.

C programs
indent -kr -i4 -nut -c50 -psl
 * Programs should be passed through the "indent" program periodically to clean them up.
 * The following indent command line should be used:
 * K&R style (Scott's a greybeard)
 * 4 character tab width, and spaces instead of tabs
 * Align inline comments on column 50
 * A newline after function definitions
