Got it. With the problem experienced yesterday, we had still this issue 
this morning. It is now fixed :).

The "-p" flag exists to specify if we have to use the admin login on 
wiki to do the command. For instance, here we fetch a page from the wiki 
with Admin privilege.
Others arguments remains the same.

Do you suggest we include the "-p" flag in <something> ?
I agree for the use of "$@".

Ok.

Sorry, we misunderstood what you mean... Update is coming. What about 
git_diff_directories ?
Because this shell function execute a special instance of diff, matching 
two directories and ignoring blank character.

Good idea for the exit status.

this function is now erased from our code... Actually, it was really 
useless...

We were supposed to do it with the previous version.
But we are facing some difficulties using die function outside the test 
harness. We wanted to include the file "test-lib.sh" in our own script 
"test-gitmw-lib.sh" to use die. It doesn't work, because the harness 
expect the file "test-gitmw-lib.sh" to be a test script. Wich is not the 
case.

Do you have any Idea about how to fix this problem ?

Agree, see above.

Change on the way. renaming this variable "is_login". Is this ok for you ?

Not at all, we juste didn't thought about it.
