You don't.  The primary goal of short form is to be short to type from the
command line, and if you are in doubt, you can always disambiguate by
saying ":/:@foo", and you can use the terminating colon even if you are
sure "@" is not a magic in your version of git.

Scripts can and should use the long form for readability and compatibility.

Exactly.  It is Ok if the short form is a bit more complex to explain than
the long form (which should be very easy to explain).  The goal of the
short form is to make the end result is short to type, once the user
understands the rules.
