[PATCH 1/3] fish-completion: deduplicate completion definition

[Johannes Altmanninger]

The completions for -c/--clip and for password names are defined
repeatedly, for different conditions:
1. for a command line like "pass show "
2. for a command line like "pass "
3. for a command line like "pass -c "

Fold the definitions into one, which paves the way for further
simplification.

No behavior change intended.
