Hi Andreas, I got too angry fighting with git-am when trying to merge
these patches (looks like [1] is not integrated in my version of Git).
Could you please push them somewhere, so that I can simply pull? I thing
there *must* be an easier way than saving patches from Thunderbird,
applying them one-by-one and writing the commit message once again :(.

Obligatory question -- what's the overhead of a QRegExp() constructor?
I'm asking because QSettings() is documented to have very low overhead,
and it's really good to have optimizations backed up by measurements.

If you allow entering multiple strings, please also make the GUI look
intuitive. Separating regular expression by semicolon isn't intuitive. I
can't think of anything better that a QTextEdit; I don't believe you'd
like me to suggest using a QListWidget with some delegate for editing
the regular expressions, although I'm sure Jesper would be glad to see
it integrated with the KRegExpEditor :). If you find something
reasonable, please go ahead and use that.

What happens with other possible stacks? What about replacing the
previous file with the new one if the regexp matches? I don't really
like creating stacks in this situation.
