Improving abbreviations/notations + backtrack of semantic change in r12439
- Deactivation of short names registration and printing for
abbreviations to identical names, what avoids printing uselessly
qualified names binding where the short name is in fact equivalent.
- New treatment of abbreviations to names: don't insert any maximally
inserted implicit arguments at all at the time of the abbreviation
and use the regular internalization strategy to have them inserted
at use time.
- The previous modifications altogether make redirections of
qualified names easier and avoid the semantic change of r12349 and
hence allows to keep "Notation b := @a" as it was before, i.e. as a
notation for the deactivation of the implicit arguments of a.
- Took benefit of these changes and updated nil/cons/list/app
redefinition in "List.v".
- Fixed parsing/printing notation bugs (loop on partially applied
abreviations for constructors in constrintern.ml + bad reverting of
notations with holes that captured non anonymous variables in
match_cases_pattern).
- Add support for parsing/printing abbreviations to @-like constructors
and for reverting printing for abbreviations to constructors applied
to parameters only (function extern_symbol_pattern).
- Minor error messages fixes and minor APIs cleaning.
