ridiculousfish	e0e4b11dbd	Make arguments to builtins const ... Prior to this change, builtins would take their arguments as `wchar_t **`. This implies that the order of the arguments may be changed (which is true, `wgetopter` does so) but also that the strings themselves may be changed, which no builtin should do. Switch them all to take `const wchar_t **` instead: now the arguments may be rearranged but their contents may no longer be modified.	2021-03-28 15:31:25 -07:00
