fix in logical_volume provider, function "exists": false matches.

[FrankVanDamme]

eg. check for lv_mysql would return true is lv_mysqllog exists.
This can be fixed by improving the regex searching for the name of the LV.

It does.
Apologies for not getting around to merging this in > 1.3.0, but the change was utterly incompatible with later revisions anyway.
