Comma-separate the list of allowed file extensions

Problem/Motivation

The list of allowed file extensions on a file field display is not very readable, e.g.:

Allowed types: gif jpg jpeg png pdf mp3 tif tiff.

Current State

Input

The input allows both comma separated and space separated file extensions in allowed files. If we enter space separated entries upon save they get stored separated by commas.

Output

The list of file extensions is always displayed separated with spaces.

Proposed resolution

Change the list to add commas between each item if they are not already present, e.g.

Allowed types: gif, jpg, jpeg, png, pdf, mp3, tif, tiff.

Input

Unchanged.

Output

The list of file extensions is always displayed separated with commas.
