This means that "if the return value of the flags_saved function is
true, return from the save_flags function". Its purpose, presumably,
would be to prevent the flags from being saved more than once in the
same run.

When a command line contains two different commands separated by an
'&&', the second command is executed only if the first command returned
a code indicating success. (Similarly, when a command line contains two
different commands separated by an '||', the second command is executed
only if the first command returned a code indicating failure.)
