conky/src/text_object.h
Phil Sutter 2f3fb23ff7 separate parsing and interpreting text objects for certain objects 
All objects parsing text into objects formerly parsed and evaluated
their arguments each update interval. This does only make sense when the
parsed text could change between updates, which is the case for execp
and execpi objects, but none of the others. So have them parse the text
when creating them, so each update interval only the output has to be
re-extracted.

In fact, this should give a performance boost when using any of the
affected objects, as parsing the input text is quite expensive since
we're evaluating templates.
