Merge branch 'mk/tcsh-complete-only-known-paths' into next
Manlio's "complete with known paths only" update to completion
scripts returns directory names without trailing slash to
compensate the addition of '/' done by bash that reads from our
completion result. tcsh completion code that reads from our
internal completion result does not add '/', so let it ask our
complletion code to keep the '/' at the end.
* mk/tcsh-complete-only-known-paths:
completion: handle path completion and colon for tcsh script
