pl.lapp error when actually passing required parameters about penlight

[rjpcomputing]

Update:

• I found out that if I run the script from the same directory it works using Penlight v0.8.4 only.

  Works:
  $ lua poot.lua # Works
  Fails:
  $ lua test/poot.lua # Fails

• I get a different error from 0.9.0. Here is the error message:
  $ lua poot.lua dsf
  lua: /usr/share/lua/5.1/pl/sip.lua:245: argument 3 expected a 'table', got a 'nil'
  stack traceback:
  [C]: in function 'error'
  /usr/share/lua/5.1/pl/utils.lua:326: in function 'assert_arg'
  /usr/share/lua/5.1/pl/sip.lua:245: in function </usr/share/lua/5.1/pl/sip.lua:242>

I am not sure if I should open a separate issue for this issue. So far I think there are 2 separate issues going on here. Please ask me questions . This got a bit more confusing.

Sorry, Ryan - last commit definitely broke lapp. The res declaration was moved into the first loop, but I then needed another res declaration in the second loop.

Latest commit no longer has the problem. As for --long-option, I will do some experiments in relaxing the pattern.

Probably related: test-lapp.lua fails on my machine at this line.

test-lapp:missing required parameter: speed

    --foo (string default 1)
    -s,--speed (slow|medium|fast default medium)
    -n (1..10 default 1)
    -p print
    -v verbose
process failed with non-zero result: ./test-lapp.lua

EDIT: please disregard that, the tests do not fail with the latest git head (only with the version of Penlight available in LuaRocks).
