More short symlink aliases; Ability to indicate sort col/dir; Hdrs don't add spaces

RELEASE-NOTES.md has full details and git log max detail, but in brief:

• Add dp, kp, fp, wp & k short aliases
• Add ability to visually indicate sort order & direction via -g,--glyph
• Fixed for both old & new header size-induced space insertion in headers so that e.g. pd|awk probably works
