--[[
Provides the following user-defined view column types:
* NameLink -- Name column that shows target of symbolic links
* MimeType -- column that shows MIME type of an entry
* LsSize -- ls-like size column (at most 4 characters in width)
* LsTime -- ls-like (also MC-like) time where time is shown if year matches
current, otherwise year is displayed instead of time
* MCSize -- MC-like size column
* AgeAtime -- relative age based on the atime stat (11 characters in width)
* AgeCtime -- relative age based on the ctime stat (11 characters in width)
* AgeMtime -- relative age based on the mtime stat (11 characters in width)
* FileMtime -- modification time for files only
Usage example:
:set viewcolumns=-{NameLink},8.7{MCSize}
