- The LTL/PSL parser now has a lenient mode that can be usefull
to interpret atomic proposition with language-specific constructs.
In lenient mode, any (...) or {...} block that cannot be parsed
as formula will be assumed to be an atomic proposition.
For instance the input (a < b) U (process[2]@ok), normally
flagged as a syntax error, is read as "a < b" U "process[2]@ok"
in lenient mode.

- When printing a formula using Spin's LTL syntax, we don't
double-quote complex atomic propositions (that was not valid
Spin input anyway). For instance F"foo == 2" used to be
output as <>"foo == 2". We now output <>(foo == 2) instead.
The latter syntax is understood by Spin 6. It can be read
back by Spot in lenient mode (see above).
