[Dctrl-tools-devel] Bug#715024: dctrl-tools: Surprising behaviour of -w -P

[Christopher Huhn, GSI]

Package: dctrl-tools
Version: 2.22.2
Severity: minor

Hi *,

I just stumbled upon "grep-available -w -P libstdc++6" not finding any package. 

Obviously '+' signs are not treated as literals but regex operators and consequently
"grep-available -w -P 'libstdc\+\+6'" properly locates the package.
"grep-available -X -P libstdc++6" works as anticipated by me.

Is this the expected behaviour? 
If so maybe the manpage should be a bit more verbose about the exact semantics 
(and possible use) of -w.

Cheers,
	Christopher
