Yes, I overseen the LASSERT(repl_buffer.readString(lyx), return 0) statement,
so I was confused.
I can handle it now, but there is one difficulty, I cannot resolve.
The search-buffer and the replace-buffer contain not only strings, but also
the font, colour, size, specs.
ATM, the spec is used from the replace-buffer (only the char-cases are handled
differently)
We need a flag to know what should be done.
Committed at 60980b0e.
The replacement strings are '$$0', '$$1', ... , '$$6'
Number 7, 8, 9 are reserved, because the algorithm eats 3 of them.
