In some cases, long filenames were being truncated early due to the
comments section being devoid of text, but having a min-width.
The file-list uses min-width on the various sections to align content
vertically in a table structure.
The rows are also displayed using flex. All of the content to the right
of the comments section has static min-widths that are usually greater
than the width of the content, meaning that any comments string will be
properly right aligned.
Removing the min-width from the comments section allows the filename to
extend into the empty space, helping avoid visibly unreasonable string
truncation.
Some padding-left is also added to ensure the sections are always
properly separated.
