${(g:opts:)…}: Process escape sequences

Without options, ${(g::)name}, processes escapes like the echo builtin.

Options o, c, and e enable processing of different forms of escape sequences.

Options

o

Octal escapes don’t take a leading zero

c

Sequences like ^X are also processed

e

Sequences like \M-t are also processed
