Use \DescribeMacro with curly enclosing argument, as @ is not a letter within documentation.
- Simplify \fc@iterate@on@languages after some discussion on fr.comp.text.tex
- Replace v2.05 by v3.00 in \changes and \ProvidePackage, as agreed with Nicola
- Correct some changes to \changes (don't know when that \ was dropped)
Correct `"\somemacro"' to `\cs{somemacro}' in code documentation
Set \languagename to \fc@mainlang when:
- \languagename has not been loaded to fmtcount,
- a language has been loaded to fmtcount by package option, and therefore \fc@mainlang is not empty, but
- neither babel nor polyglossia is use
Make more testing:
- test language loading via global option
- test language loading via babel (with tex4ht test engine)
Also: improve test cleaning
