2378. Inconsistent grammar for reference init-capture of pack

[Accepted (as paper P2095R0) at the February, 2020 (Prague) meeting.]

The grammar for init-capture is:

capture:
..._opt init-capture

init-capture:
identifier initializer
& identifier initializer

As a consequence a reference init-capture pack is written as

  [...&x = init]

instead of the way packs of references are commonly written:

  [&...x = init]

Notes from the November, 2018 meeting:

CWG agreed with the suggested direction.
