Nice move to include a test with an indented key phrase. The t4018 test
cases all look fine. I don't speek Kotlin, though, so...

I know you just copied an existing test case. But actually, it misses
the important parts of the word regex patterns. In particular, it only
tests that a change of a to x is found, but does not test that the
operators are not split into individual characters. Please have a look
at my series 1cf93847c1ed~..386076ec92c7 and in particular 1cf93847c1ed
to see what you actually want to test. For example, you could test a
change from a+=b to a-=b, i.e., that operators += and -= are not split
into +, -, and =.

I would guess that the trailing [ \t]* is pointless and always empty,
because it is covered by the preceding .*, so you can remove it.

The first part intends to match integers and floatingpoint numbers. Word
regex can be loose. This one, however, is too loose. For example, it
treats -e+2 as a single token, but that is actually a whole expression
consisting of several tokens and is not unlikely to occur in real code.
See also 350b87cd6585.
I am pretty sure that, e.g., -1 and +2.5 are both two tokens each, i.e.,
the sign is not part of the number token.
Also, it looks like 3.0e5 is a floating point number; is 3.0E5 not?
