Bug #5420: RubyGems misleading error message for "update -l"
https://bugs.ruby-lang.org/issues/5420#change-34822

I accidentally used option -l for "update":

11:00:34 ~$ gem19 list -l facets

*** LOCAL GEMS ***

facets (2.9.1)
11:00:44 ~$ gem19 update -l
Updating installed gems
Updating facets
ERROR:  While executing gem ... (Gem::GemNotFoundException)
    Could not find a valid gem 'facets' (>= 0) locally or in a repository
11:01:15 ~$

The issue is with "... or in a repository": apparently the repository was not even searched because without "-l" it works:

11:01:15 ~$ gem19 update
Updating installed gems
Updating facets
Successfully installed facets-2.9.2
Gems updated: facets

11:03:56 ~$ gem19 list -l facets

*** LOCAL GEMS ***

facets (2.9.2, 2.9.1)
11:04:21 ~$
