[PATCH v5 00/31] Follow perlcritic's recommandations

Not many changes since v3. This version is only for fixing last typos and applying Junio's recommandations for [21/31], which I forgot in v4. At this point, the only patch worth reviewing is [21/31].

Changes with v4 : 
- fixed typos
- Change in [21/31]: all the processing is done within the subroutine

Changes with v3:
- Remove whitespace in [18/28]
- Typo in [09/28]
- Better line split in [22/28]
- A part of the file @@ -610,9 +610,9 @@ had escaped patches [22/31] and 
[23/31] for some reason. This is fixed.
- patch [29/31] and [30/31] are new: they add a .perlcriticrc file to ignore
some rules and add a rule in the Makefile for perlcritic
- patch [31/31] is also a new one, which intends to make some error messages 
more precise. It comes from an advice from es in the reviewing of v1, that I 
had forgotten to add in earlier versions. It is not related to perlcritic, but I
hope it can be included into this series of patches anyway.

Changes with v2:
- Remove patch [02/22] about using the Readonly module
- Split commit [07/22] into 5 different ones
- Split commit [14/22] into 2 different ones
- Patch [17/22] was *not* split: tell me if it is necessary
- Remove wrong change in patch [22/22]

Changes with v1:
- split first commit into 6 different commits
- remove commit [17/18] about moving open() call
- took every other comment into account
