Does epgsearch save any status from epg-data and/or timers?

This point (don't recreate deleted timers, unless wanted) was an design
criterion for Master-Timer from the beginning, so what i did in
Master-Timer is(*):
a) Mark the epg-data events that are already processed.
b) Save the timers-list

So in normal operation the marks from a) already prevent any unnecessary
processing and when the configuration was changed only intersection of
new timers are programmed(, or deleted or modified).

As i don't know for what user-type epgsearch is, i can't say if you
should go to the length of creating a proper state to operate on, or if
more or less stateless is "good enough".

*: oversimplified!

Real Programmers consider "what you see is what you get" to be just as
bad a concept in Text Editors as it is in women. No, the Real Programmer
wants a "you asked for it, you got it" text editor -- complicated,
cryptic, powerful, unforgiving, dangerous.
