Improve abbrevs for install and help

The existence of 'install-test' and 'install-clean' make 'npm inst' no longer
de-reference to 'npm install'.  Similarly, the existence of 'help-search'
prevents 'hel' from being a shorthand for 'help'.

This adds some artisanally hand-crafted abbreviations for these cases.

Fix: #1617
