[librecat-dev] fixes and tests

[aina at openmailbox.org]

Hello again,

i think the example of the use of combination of fixes and tests, would 
be enough if an example of a search and replace fix would be used:

if marc_match('100a','AWrongSpelledName')
         marc_set('100a','CorrectlySpelledName')
    end

I think an output similar to this, would be a good result.

Did the following changes to the mrc file

001: 12345, tag 100$a AWrongSpelledName, changed to CorrectlySpelledName
001: 76767, tag 100$a AWrongSpelledName, changed to CorrectlySpelledName
...

did not find in the final mrc a 100$a that has AWrongSpelledName. after 
having made 1023 changes of AWrongSpelledName to CorrectlySpelledName.
Test one passed.

same for 245$a,

etc.

I have made some attempts, but would appreciate on your approach on 
this, how i could be achieved in the most efficient way.

Thank you
