[mu4e bug] wrong-number-of-arguments in mu4e--prepare-draft-buffer

[robstewart57]

Describe the bug

Using mu at commit 14a882f , attempt to reply or reply-to-all. This message is printed:

mu4e--fcc-path: Wrong number of arguments: #<subr delete>, 0

How to Reproduce

Here's the backtrace:

Debugger entered--Lisp error: (wrong-number-of-arguments #f(compiled-function (elt seq) "Delete members of SEQ which are `equal' to ELT, and return the result.\nSEQ must be a sequence (i.e. a list, a vector, or a string).\nThe return value is a sequence of the same type.\n\nIf SEQ is a list, this behaves like `delq', except that it compares\nwith `equal' instead of `eq'.  In particular, it may remove elements\nby altering the list structure.\n\nIf SEQ is not a list, deletion is never performed destructively;\ninstead this function creates and returns a new vector or string.\n\nWrite `(setq foo (delete element foo))' to be sure of correctly\nchanging the value of a sequence `foo'.  See also `remove', which\ndoes not modify the argument." #<bytecode 0x13d36d3ec075>) 0)
