mishandling pipe character in list item

[dcg-csc]

Pandoc 2.11 seems to have a problem with markdown list items that have a code wrapped pipe character

Example input file test.md:

* `--argument` This item does not have a pipe character
* `--argA | --argB` This item has a pipe character

Command used: pandoc -f gfm --atx-headers --reference-location=block -s test.md -t gfm -o testout.md

Contents of generated 'testout.md`

-   `--argument` This item does not have a pipe character

\* `--argA | --argB` This item has a pipe character

Expected output:

-   '--argument' This item does not have a pipe character\
-   '--argA | --argB' This item has a pipe character

This worked as expected in pandoc 2.9.2

The only work around I found is:

* `--argA ` \| `--argB` This item has a pipe character

Which generates:

-   `--argA ` \| `--argB` This item has a pipe character

This was partially addressed in a commit that modifies the documentation:

-- | Syntax for pipe tables.  Note that this should generally be
 -- placed AFTER the syntax spec for lists, headings, and other block-level
 -- constructs, to avoid bad results when non-table lines contain pipe
 -- characters:  use @defaultSyntaxSpec <> pipeTableSpec@ rather
 -- than @pipeTableSpec <> defaultSyntaxSpec@.

I kept the issue open, pending a better solution, but in the mean time we should be able to fix this in pandoc by doing what this comment suggests.
