Suppose, we want to test a key sequence which should produce
logs in defined sequence. ATM, we use pcregrep to see, if
a pattern occurs in the log-file. This is OK, if using only single
tests with only one message to care about.
But it is not OK for combined tests.
As an example, the file 'findadv-combine-in.txt' is combining
tests findadv-re-01-in.txt, findadv-re-02-in.txt and findadv-re-03-in.txt.
This test runns here about 25 seconds, while the time for the other three
is about 144 secs.
(Most time is with starting/stopping lyx)
