If you want to enable all Lintian tags, just remember the phrase:
Some sponsors are “evil and pedantic”
Or on the command-line:
$ lintian -EvIL +pedantic ...
It works for Lintian 2.5.5 (and newer), which handles “pedantic” like other severities. If you need help understanding the tags, you can add an extra “i” (-i) to “evil”. That being said, remember that experimental (-E) and pedantic (-L +pedantic) tags are what they are for a reason. Also quite a few people will probably find verbose (-v) too noisy. However, leaving any of them out would have ruined the mnemonic. 
Of course, you can also ask Lintian to enable all tags via your lintianrc file. Here is a quick-start:
display-info = yes # or no display-experimental = yes # or no pedantic = yes # or no verbose = yes # or no
