auth-source-secrets-listify-pattern is a compiled Lisp function in `
Convert a pattern with lists to a list of string patterns.
auth-source patterns can have values of the form :foo ("bar"
"qux"), which means to match any secret with :foo equal to
"bar" or :foo equal to "qux". The secrets backend supports
only string values for patterns, so this routine returns a list
of patterns that is equivalent to the single original pattern
when interpreted such that if a secret matches any pattern in the
list, it matches the original pattern.
