 """style and portability checker for Mercurial
 
 when a rule triggers wrong, do one of the following (prefer one from top):
  * do the work-around the rule suggests
  * doublecheck that it is a false match
  * improve the rule pattern
  * add an ignore pattern to the rule (3rd arg) which matches your good line
    (you can append a short comment and match this, like: #re-raises, # no-py24)
  * change the pattern to a warning and list the exception in test-check-code-hg
  * ONLY use no--check-code for skipping entire files from external sources

 Systematic behavior validation of most possible cases
 =====================================================
 
 This section tests most of the possible combinations of working directory
 changes and inter-revision changes. The number of possible cases is significant
 but they all have a slighly different handling. So this section commits to
 generating and testing all of them to allow safe refactoring of the revert code.
 
 A python script is used to generate a file history for each combination of
 changes between, on one side the working directory and its parent and on
 the other side, changes between a revert target (--rev) and working directory
 parent. The three states generated are:
 
 - a "base" revision
 - a "parent" revision
 - the working directory (based on "parent")
 
 The file generated have names of the form:
 
  <changeset-state>_<working-copy-state>
 
 Here, "changeset-state" conveys the state in "base" and "parent" (or the change
 that happen between them), "working-copy-state" is self explanatory.
 
 All known states are not tested yet. See inline documentation for details.
 Special cases from merge and rename are not tested by this section.
 
 There are also multiple cases where the current revert implementation is known to
 slightly misbehave.
 
 Write the python script to disk
