Bug#532771: pkglab: version specification needs single quote for versions

[Filippo Giunchedi <filippo@debian.org>]

Package: pkglab
Version: 1.4.1-1
Severity: normal

Hi,
I was browsing pkglab documentation /usr/share/doc/pkglab/pkglab.html
though the version specification example doesn't seem to work:

> select([. kde (>= 5.2) .]) 
Exception: Interpreter.Sorry("Can't find unit \"5.2\"")
>

while with single quote it does

> select([. kde (>= '5.2) .])
{ }
> 

am I missing something obvious or the syntax has changed? (the same
error is reported also in #help:

  [.unit(operator version).]    Version specification (e.g. [.kde (>= 5.2).])
                (version part is optional)

also note that without version specification trailing space is
compulsory though the usage seems to suggest differently:

> [.cdbs.]  
Exception: Interpreter.Parse_error(7, 8, "Syntax error")
> [.cdbs .]
[. cdbs .]
> [. cdbs.]
Exception: Interpreter.Parse_error(8, 9, "Syntax error")
> 

thanks,
filippo
