The following patch series adds the SLRE "Super Light Regular Expression" library and uses this to add regex support for the "env grep" (aka "grepenv") command, and new functions (or operators?) "gsub" and "sub" to the "setexpr" command.
The rework to "env grep" also fixed a few bugs (which cuased it to dump always _all_ environment varioables on some systems), and adds the capability to grep in either the variable name, or the value, or in both (the old version olways did the latter). Instead of special functions we now use common code (i. e. hexport_r()) for the variable lookup, which gives us sorted output as a free additional benefit.
It is awesome :-)
I just found some indenting formating changing in the code mixed with code change, it'd be good to keep those in specific patches. It is easy to see in the last patch of serie, for example.
