Function descriptions do not show in completions even when created in command line

[pronobis]

When starting fish with sh -c 'env HOME=$(mktemp -d) fish', adding a function either in config.fish or directly in the command line does not produce any description in the completions. For example for a function:

function foo --description="bar"
    echo "foo"
end

Produces:

> foo [tab]
foo
foo2hbpl2               (Convert Ghostscript pbmraw or bitcmyk format into a ZJS printer stream)

This problem does not seem to be related to #328 since the function is created in config.fish or directly in the command line.

Version:
fish, version 2.7.1

This was a regression caused by some previous refactoring but I wasn't able to bisect it as somewhere in the middle completions would sigabrt fish for me. Fixed in all cases.

@pronobis thanks for reporting and bringing this to our attention. Feel free to try using the fish nightly builds including 9c63ad3 to see if this is fixed for you.
